I'm trying to start a server using mcmyadmin but anytime I attempt to add sponge it gives me a ton of parsing errors as shown below, Any insight would be appreciated.
Your using Sponge this voids support unless you can reproduce bugs/issues in Vanilla Forge. Parsing error is also fine to ignore this is known/not an issue. So you'll be fine. But if you find any bugs or whatnot; don't report them unless you have Sponge removed.
