Ugh, my brain wires for searching first really don't work this year, do they? Normally I google stuff up-front, but when it comes to more special things, the concept of search feature somehow competely escapes me
I'm not sure I understand though: the game consists of tens of GBs and that stuff loads in matter of seconds. How can few tens of MBs worth of savedvars make an impact? I mean, unless the LUA code is extremely inefficient, writes everything at once repeatedly etc...
Btw in the case of LibDebugLogger, I wasn't able to figure out how to make it stop writing anything. There doesn't seem to be an option for that unfortunately. I guess it adds up. If I delete the file, it gets recreated and grows up to few hundreds of kBs each session.
