Short update.
We cant run it with couldron without the known fluid bug.
The version we can use is with forge 1343.
That conflict with some mods.
The 3 mod we downgraded are:
extrautilities (extrautilities-1.2.3.jar)
CodeChickenCore (CodeChickenCore-1.7.10-1.0.4.29-universal.jar)
EnderStorage (EnderStorage-1.7.10-1.4.5.27-universal.jar)
With these three changes the server is running very well and stable + big performance boost from cauldron.
But the clients need to do the same.
Could you consider to change that in your pack?
And a little mod recommendation:
waila plugins
