Forge server won't even start


#21

Try creating a new folder for your testing and completely setup a new Sponge / Forge server as I just tested with the versions of forge and sponge you mentioned and had no issues.

forge-1.12.2-14.23.2.2611-universal.jar
spongeforge-1.12.2-2611-7.1.0-BETA-2990.jar

These are what I used.
