Minecraft version: 1.12.2
Wizardry version: 4.2.9
Environment: LAN game

Issue details:
Possession makes friend playing with me on LAN get the same "possessed" filter/visual effect. The issue is it stays active on my friend even after I am done with it. It doesn't matter if the possessed mob is passive (squid) or aggressive (slime). Logout, login is a workaround for this issue.

Other mods involved: none relevant, using MC Eternal modpack.

Duplicate of #179, which is fixed in the current release (4.2.10).
