I will present my log. Basically, vanilla has been known to crash for me, sure. But, for some reason it crashes almost 100% when I run a server mod. Anyone, dev or otherwise, have any results as to why this occurs?
The most common cause is missing commas and other json syntax errors, but this often leaves an error message. I get jsonlint set up when doing manual edits. There are three minor mod errors logged during start up. It wouldn't hurt to get those cleared up first. If all that fails, make sure you've got a source commit or other backup, and then start deleting groups of your files (to let vanilla through) to narrow down the problem.
I know about the minor errors, never hurt anything and I believe they are from other mods or vanilla and not my own. No major error like I am used to seeing in the log is coming up. Just a crash number. I am still unsure it is my mod entirely, I tried reverifying, it hasn't crashed yet. If it does, I will be testing chunks of files and seeing what removed fixes the crashes.
