Whoops, just noticed the typo in the title, that's supposed to be 'data.raw'
Anyway:
Line 500 of data-final-fixes is making the log file very large, please comment it out in your next release:
-- log(serpent.block(data.raw, {comment = true, refcomment = true, tablecomment = false}))
Someone who has about 200 mods installed sent me their log file because they're having problems with my mod, and your one log call here made about 9 million lines of log output, haha
You have a lot of other log lines that could be cleaned up, but you can worry about those after you get more experience
