Well, something hates TCG

Build 175

Lemme guess, something in TCG hated whatever was going on?

TCG was just calling a Mojang method (the same one that is used by Vanilla Minecraft to grow huge fungus trees). My guess is that Spigot/Paper/Pufferfish doesn't expect a plugin to call the same method and was flagging it as a warning for doing something that it thought was unusual. Probably more of a Spigot bug than a TCG one IMO.

I just switched to using a different Mojang method (one that was called by the original method I was using internally anyway) and bypassed a few lines of vanilla code - no more warnings :)

Ah.
