Its not working on my Cauldron 1.7.10 Server

Missing Mods:

Forge : [10.13.4.1614,)

Really sad story.

Update your forge to that version then. Also don't expect Cauldron to work with this or any forge mod either. At least not smoothly.

This is not our problem. Use a real Forge-Server instead. Cauldron is highly not supported. Don't expect other ports like CKauldron/Thermos to work too with our Mod. Use them on your own risk.

"Missing Mods:
Forge : [10.13.4.1614,)"

Literally telling you that you need to update your cauldron to a version that uses forge 10.13.4.1614.
I can't facepalm hard enough.

Also, what @NitroxydeX said, even with the correct version, there's a lot of bugs on it that will not appear on real forge.

I switched to KCauldron on same day and solved the problem. I thought that Cauldron dont have a version which support "Forge : [10.13.4.1614,)". Now the mod works fine, don't found any bugs at the moment.
