Hi!

Darkosto has been using this mod in an upcoming Modpack where the world is generated as large hexes, we use your biomes for some of the hexes.
We have encountered a generation issue when a Gummy Swamp spawns next to a Void hex and the WorldGenGummyWorm happens to run on the edge of the biome the server thread enters an infinite loop.

With some debugging and thread dumping I've found that the findSurfaceBlock() method will run infinitely if it's over a Void. The isAirBlock() check in isAirOrLiquid() always returns true when below 0 so I suggest to add a check of Y being above 0.

I know this very special edge case and not intended by the mod but would appreciate it being fixed.

It should be fixed, although I didn't really do any testing. I've uploaded a patch to curseforge.
