I have a odd issue with FTB Revelation (Minecraft 1.12) and we tried serveral of versions of Forge ans Sponge (to match their version numbers) but after it starts the TPS drops to a unplayable 4.0.
When I remove Sponge from the Forge-mod directory the TPS goes back to 20.00 but I have no clue what this it.
I have no Sponge plugins installed so its only the FTB Revelation (1.6.0) pack with the matching Sponge version.
Is this a known issue in MC1.12? We are now running without Sponge but I really would like to use the Sponge plugins since we use them in our other server aswell.
