Memory issues during save / load

HI there,

I played the last episode of the HoG campaign only to find it crashing due to low memory. The crashes, which I have never experienced before with the very same hardware setup, occur usually at the time of save or load game. For some reason, Steam crashes as well and need to be restarted. Every crash was preceded by a system message saying WFTOGame.exe taking too much memory.


Save Crashes

First time it happened when I saved a game on a free slot. The game crashed when I clicked the "Continue" button just after the saving process was complete. Unfortunately, the save file was not created - so I lost my progress.

Once it happened, I restarted the level and saved the game more frequently, overwriting the previous save every time. One of these times the game crashed leaving me with no save file... It happened a few times again later on - the game crashed due to low memory when saving.


Load Crashes

Loading a save fame of a heavily crowded dungeon, results in a "Low memory" message from Windows and a crash. Usually it happens when the loading bar is full and you can hear the game sounds.


I attached the log file of the recent crash; unfortunately the saved game disappeared so I could not attach it (funny, it crashed when I wanted to save the game to report another bug :) )

It's possible that could have contributed to the situation then, but we'll know better once one of the coders takes a look at your log.

Hi Elicn, sorry to hear you're having issues with the game.


I took a quick look at your output log, and I saw a lot of repeated null reference errors, i'm no expert as i'm not one of the coders, but I think it's possible that those errors were repeating infinitely using up all the available memory until your system ran out causing the crash. As the data is being uploaded to the Steam cloud that would probably explain why it crashed as well.


Saving and Loading data is one of the most resource intensive parts of the game but with 8gb of RAM I wouldn't expect it to be running out of memory whilst saving under normal circumstances. IN this case it seems like the saving process is failing midsave, leaving you with an only partially saved (and therefore corrupted) savefile which the game is then unable to load properly.


Had you claimed a lot of the map and recruited quite a large army? that could be a factor as obviously that means there is more data to save and HoG4 is quite a large level.


In the mean time i'll pass this report through to the code team to take a look at and hopefully they'll have a better idea than I do what's causing your issue.


Thanks for the report.

Yes; in fact the dungeon was fully claimed and was quite crowded with friendly units.
