Rlcraft sever unale to add sponge

I am currently running

  • SpongeForge version: spongeforge-1.12.2-2838-7.4.7.jar
  • Forge version: forge-1.12.2-14.23.5.2860-universal.jar
  • Modpack: RLCraft V2.9.3

Crash report:
[12:17:15] [main/FATAL] [mixin]: Mixin apply failed mixins.rlmixins.core.entitytracker.json:vanilla.PlayerListMixin → net.minecraft.server.management.PlayerList: org.spongepowered.asm.mixin.injection.throwables.InvalidInjectionException @At(“INVOKE”) on net/minecraft/server/management/PlayerList::doPrepareLeaveDimension with priority 1000 cannot inject into net/minecraft/server/management/PlayerList::transferEntityToWorld(Lnet/minecraft/entity/Entity;ILnet/minecraft/world/WorldServer;Lnet/minecraft/world/WorldServer;Lnet/minecraftforge/common/util/ITeleporter;)V merged by org.spongepowered.mod.mixin.core.server.management.PlayerListMixin_Forge with priority 1111 [PREINJECT Applicator Phase → mixins.rlmixins.core.entitytracker.json:vanilla.PlayerListMixin → Prepare Injections → → redirect$bdm000$doPrepareLeaveDimension(Lnet/minecraft/world/WorldServer;Lnet/minecraft/entity/Entity;Z)V → Prepare]

The server runs fine with only sponge, and with the modpack without sponge, but as soon as I add it the server is unable to start all the way up. I have renamed the sponge jar file to appear first in the list of mods . Thank you in advance for your advice!

Its not enough information to go on. Mind sharing the whole log (ideally via a pastebin site so formatting isnt destroyed)? Not just the error

Looking at the issues in RLCraft, it seems to be a issue they are aware of and you need to disable an option in the config
