1.18 support: ClassNotFoundException: Could not resolve class for net.minecraft.server.v1_18_R1.Entity

[Dymeth]

Paper version git-Paper-84 (MC: 1.18.1) (Implementing API version 1.18.1-R0.1-SNAPSHOT) (Git: ae6fec6) PacketListenerApi v3.9.9-SNAPSHOT MapManager v1.8.5-SNAPSHOT

Looks like MapManager can't enable on Paper 1.18 due to packages location changed in NMS:

Same issue. Meanwhile that plugin is necessary for AnimatedFrames to work, which is fluking pinned on InventivetalentDev github page!

I hope it won't be long until a new version releases for 1.18.x

@InventivetalentDev Can you please look into this issue?

It works with the latest version 1.8.6-SNAPSHOT (https://github.com/InventivetalentDev/MapManager/releases/tag/1.8.6-SNAPSHOT)
