Forge: 43.2.0
Placebo: 1.19.2-7.3.3
Apotheosis: 1.19.2-6.4.0

Game crashes on startup complaining that I don't have the right version of Placebo.
debug.log

Followup: noticed that the forge version was outdated as well and updated to 43.3.0. Same result.

If I'm reading the log correctly its saying the Placebo jar you have is actually an Apotheosis jar.
I have no idea how that could've happened, but I can verify that the jar on CF is correct, so try reinstalling Placebo, I guess.

Not sure how it happened but I redownloaded and everything is peachy, gremlins in the machine I guess.
