Hi, we are having an issue with pumpkins on the server, where mousing over or picking up a pumpkin from your mod will crash the client.

Server is SpongeForge with 1.12.2
Other Mods:
Chisel 1.12.2-0.2.0.31
Chiselandbits- 14.16
CTM-MC1.12-0.2.3.12
Decocraft-2.5.5_1.12.2
LunatariusCore-1.12.201.2.0.42
Optifine-1.12.2 HD U D1
Pams Harvestcraft1.12.2t
Pet buddy 1.12.2
Pixelmon 5.2.3
Subcommonlib-sublib-1.12.2-1.2.0.4
TCG 1.12.2 2.1.0
WIT 1.9.4-1.0.23-44

Attached are the crash logs of different users and different times
crash-2018-04-09_12.59.40-client.txt
crash-2018-04-09_13.02.20-client.txt
crash-2018-04-09_13.05.14-client.txt
crash-2018-04-09_15.01.47-client.txt
crash-2018-04-09_22.16.20-client.txt
crash-2018-04-09_23.00.52-client.txt

Clients should also install the correct forge version. Doubleclick on spongeforge.jar can help.

For information about Pixelmon the hobby of Notch should be enough.
