I also get a crash at the same time every time i load a save. And yes I use mods, every mod in Tacyn's Mod v.2. Mods was downloaded today so the date for the mods (if you want to find versions) are the same as this post, the site to upload saves are down so tell me where to send it if you want it.
Do you mean you just added mods to a world? Or that you just updated mods for a world?
Both of those are likely to cause a crash. Only Tacyn would know for sure.
This line right here looks to indicate something is wrong with a resource in the tacyn mod. vid System.ThrowHelper.ThrowInvalidOperationException(ExceptionResource resource)
Does the mod say it works with the 1.0.0.0 release of Gnomoria? or is it for an earlier release?
If its not a mod-version conflict, i remember there being localization issues with some characters. You could try setting your windows system language to US-english, with the default US-character stuff. I think the error was specific to decimal place separator, but I'm no longer sure, and too lazy to look it up.
There is very little support for the game as the developer has moved on. Also not very many people lurking the forum anymore. Best of luck.
