Hello Thadir,
which OS are you using (Win XP, 7, 8.1, 10) and is it 32 or 64 bit?
Can you upload your logs as specified here https://forum.subterraneangames.com/threads/please-read-how-to-report-a-bug.4689/
?

Cheers

Hello Julianb3000,
we got a similar report recently, which we fixed already:
https://forum.subterraneangames.com/threads/unclaimable-neutral-tiles.9864/

However when the old bug forums was locked, I continued the thread with the reports in a private conversation on forum.
We figured out this is a map editor bug which creates invalid claimed tiles which are "fortified" (which is only meant for walls) when you paint claimed tiles over fortified walls.
Since these claimed tiles have the fortified flag (you can identify those when tooltip shows "[Fortified]" http://imgur.com/8732oYj) some game machanics considers them as walls.

Now there is a game mechanic that makes sure:

When ever you claim a new tile all adjacenting walls which do not have

at least one claimed tile of their owner in 8 neighbors around is automatically unfortified.

(you might have already seen that enemy walls are unfortified when you claim around them)

So when you claim any neighbor of of such "fake fortified wall" the game

will in this process "unfortify" the claimed tile, which does simply remove ownership.

What remains is a claimed tile without an owner, something which should never exist.

Workers who try to unclaim can't do it and will get stuck.

We fixed the issue on both two ends.

- Fixed that the map editor can create such tiles

- Made sure that a tile having the issue is automatically fixed on map loading

I guess you have the same issue and it is fixed already.

A patch will be coming quite soon.

Hint:
Until patched, you should be able to fix affected tiles simply by applying the Annex spell on them.

Please let me know if you think it is not this bug we have fixed.

Cheers

PS. I was not able to open your link as it points to "myworkshopfiles" which something you can only access private

Just for others reading this:
So what did you do to fix the issue?

For the saving issue:
When you did your report on the old bug forum your logs clearly said you did run out of RAM.
If you have now more RAM saving should work flawlessly.
Do you still have issues?
If yes, please upload another output_log so we can see why.
In this case, under Control Panel -> System what does it say how much RAM you have usable?
Cheers

We only know that it is an issue where an RPC is not passing through the peer to peer connection.
So far everyone who fixed it said it was a firewall:
https://forum.subterraneangames.com/threads/no-gold-no-buildings-in-multiplayer.9861/#post-94715
Thus try to add a new firewall rule allowing everything incomming and outgoing from/to WFTOGame.exe
Then it should work if there is nothing else blocking or filtering your peer to peer connection.

if you don't know how to make sure this is not the case, switching client and host or restarting the game might fix it.

So you are still using Windows XP 32bit?
Well disk read error can mean either there are insufficient rights or an issue with your hdd.
It should have nothing todo with your RAM.
Did you tried to verify steam cache after a fresh reboot and with starting steam as administrator?
If this didn't help, it might be needed to check your HDD for any defects.
See: https://technet.microsoft.com/en-us/magazine/ee872425.aspx
Use chkdsk with repair option: chkdsk /f C:
If this finds and repairs an issue, then try again to verify steam cache after a reboot by running steam as admin.
Does it help?

I just ask to be sure:
And in the in-game Display Options you have set it to fullscreen?

Also can you hold shift before clicking on "Play" in Steam and keep it hold until a little configuration window pops.
In this window you can chose your resolution and uncheck a checkbox "Windowed".
Does it help to get the game into fullscreen?

Oh I was almost sure you would just suffer from the issue Coherent UI has with 4K resolutions.
1920x1080 should work for sure! However sometimes Unity engine has system specific issues on OSX.
We do not have too much control about this on our end. We just use the API provided by the Unity engine.
Do you have other Unity3d based games which do not suffer from the issue?

Resetting your home realm must have fixed it.
If you encounter this again, it would help to upload your home realm save + the output_log file again, so we can try to track the issue down.

Cheers

Hello Tomasz Janusz,
4K resolution can not be suported yet due to our UI middleware "Coherent UI" doesn't support it yet.
If you play on full HD resolution everything should work fine.
Cheers
