LiquidBounce is incompatible with ReplayMod. You could join with a second account and use it for recording. We might be able to solve this problem with an update but it doesn't have high priority.
Not compatible, because autosettings made for 1.8.9. Use 1.12.2 b73 port or play 1.8.9 b73, lol
EDIT: b2 1.12.2 is not compatible with 1.8.9 autosettings, but 1.12.2 b73 IS compatible
