I entered a Mysterious Portal on Level 6 (fungal). I cleared the area but found no exit portal anywhere, so I exited by adding -debug-flag to the launch options and pressing p to return to Level 6. I saved and quit, and removed the launch options. Now the game closes randomly as I walk around Level 6 (it doesn't seem to crash on the higher Levels). It doesn't seem to freeze or hang, it just closes like the process was ended through Task Manager. I loaded a different character with the same mods. They're on Level 3, hasn't entered a Strange Dimension yet. No crashing on that one either. EDIT: I finally got some sort of error message, from Microsoft Visual C++ Runtime Library: Runtime Error! Program: ...mapps\common\Dungeons of Dredmor\Dungeons of Dredmor.exe This application has requested the Runtime to terminate it in an unusual way. Please contact the application's support team for more information.
Sorry for the delay! It's too big to upload on the forums, so I've put it on MediaFire. The mods I play with are Jay's Mega Phoneme Mod, More Dred, Interior Dredmorating, Roguish Renovation, and Advanced Craft'n'Smelt.
