Cannot Replicate

Impenetrable rock appearing in level after reload

I have a custom a pet dungeon I play with. After a reload sometimes blocks of Impenetrable rock will appear at random locations in the level. I can remove it with god mode, but It is still annoying.

Hi Midapiet,

Can you identify the level in question for us and upload an affected save file?

I can't say whether it's the exact same issue, but occasionally when loading any level in the map editor (not just MPD), it will sometimes drop one or two Impenetrable Rock blocks at seemingly random positions on the map.

My save\map is technically a scenario rather than a pet dungeon level I made as I wanted to make a pet dungeon version of one of my custom maps:https://steamcommunity.com/sharedfiles/filedetails/?id=1576454457

I use god mode to spawn in anything I want.

(by the way, is there an easy way to copy custom maps to make an alternate version?)

To make an alternate version you can use the "import" function.

I see, thanks!


Thanks for the files and further information.

I've assigned this ticket to our triage queue when we come to our our triage pass sometime in Q1 2019.

I got an update. It might be a coincidence, but it seems the glitch happens when I have a high creature population in my dungeon.

I cannot open your map. If it is happening in a map that was updated from the old pre 2.0 formats then theres nothing we can do

Sorry for resurrecting this thread, but I found a possible lead on the impenetrable rock bug.

While I would need to do further testing to rule it out completly, it seems I am not affected by the bug if I don't install the undergames expansion.

It would make sense, since I remember I first noticed the bug around the time I bought that expansion.

Hi Midapiet,

I've confirmed with the code team that unfortunately, there's no possible cause rooted in whether the Undergames DLC is enabled or not. 

Whether the DLC is enabled or not does not actually change anything with how the game or save files work and is completely separate from these systems. It's more likely that this would be the result of a rare intermittent issue and coincidentally seemed to fix the problem but did not actually address the underlying issue.

Unfortunately this issue is practically impossible for us to identify with our current resources. Though I'd certainly welcome any save files which have the issue occuring that we might be able to investigate further.



Try with this map, if you would - it was only recently released and I can confirm the Impenetrable Rock glitch happening on save/load on or next to the gateway located almost directly above the Dungeon Core, even when not having done anything else on the map; the creator said they "squeezed everything I could out of (the editor) without breaking the map itself", so it might help if it's a memory issue or something.


Disregard - the map was updated and the glitch appears to have disappeared.

Unfortunate. Thanks for keeping us in the loop though.

Steam. Windows7 64. Game v 2.0.7f1.

Pet dungeon "Deepwater" default mode. 6+ hours. After another save load impenetrable rocks all over the place. 

Have all DLCs installed except cosmetick imp ones. Dont know what else to add.

Tried to replicate but no luck. I can only presume it's related the number of hours played.

Any chance you can upload the save files affected for us? How to: Locate your save files
