well Congratulations. you managed to find a very difficult bug to track down. ive spent like 3 hours downloading and enabling mods and cant reproduce that crash. right now i have 5dims, aaii + remaining aai stuff, bobs, bioindustries, angels, omni, and pymods all loaded without issue.
if you'd kindly disable omni and send me a save here or pm on the forums with the rest of the mods your trying to use so i can use the save sync to find them all it will save me sometime.
also if your feeling spunky enable the omni mods one by one till it crashes again will narrow down the problem
i cant get omnicompression to load it just sits here doing nothing for me for like 20+ mins so idk if its the problem or not.
the crash log unfortunately doesn't really indicate where the problem is and all the error is stating is that onmi doesn't like one of the angels functions im calling in my mod. doesn't say which one or what doesn't like it and its fine with the above listed mods active.
