I had an error in my mod code, log.html showed proper error with a stack trace to me. However, after fixing and replacing the zip file I still see the same error on the same line, which doesn't make any sense. I tried packing as zip and unpacking into data dir, starting a new campaign. I tried updating the mod version - MSU correctly shows it. But nothing helps short of removing the mod. Does anyone has any idea what is happening?
