Game is locking up and the single player internal server is crashing due to STEP_Hight when joining a world or joining an existing world. Looks like some bad interaction between flib and cyclic, but i'm not really sure?

Downgrading FLIB to version 1.20.1-0.0.12 from version 1.20.1-0.0.13 fixed the issue. FLIB's fix to the issue of Four PlayerUtil functions added; fix crash error with dependency CustomGameRules. Which that fix FLIB made might have broken a feature in cyclic? Not really 100% sure.
