Here is get a problem with cauldron ( server part ) from here tcpr.ca/cauldron . All version 1388 and above have problem, that bonus sets dont work and dont give any bonuses, with lower version alright.

Cauldron has been abandoned, after the DCMA. That is likely an illegal download site. Since DRPG has been tested and works on normal Forge servers, this isn't a real issue, I have no reason to support obsolete software which seems to be bugged.
