@Levas/Alis No errors from RST. I
suspect that using modded civs that have no parameters needed for RST is causing problems.
You can either not use them (always an option) OR add required parameters manually in the file RealStrategy_Leaders.sql.
There is a section with flavors for leaders, that goes like this:
INSERT INTO RSTFlavors (ObjectType, Type, Subtype, Strategy, Value) VALUES -- generated from Excel
('LEADER_BARBAROSSA', 'LEADER', '', 'CONQUEST', 6), ('LEADER_BARBAROSSA', 'LEADER', '', 'SCIENCE', 7), ('LEADER_BARBAROSSA', 'LEADER', '', 'CULTURE', 4), ('LEADER_BARBAROSSA', 'LEADER', '', 'RELIGION', 2), ('LEADER_BARBAROSSA', 'LEADER', '', 'DIPLO', 2),
('LEADER_CATHERINE_DE_MEDICI', 'LEADER', '', 'CONQUEST', 4), ('LEADER_CATHERINE_DE_MEDICI', 'LEADER', '', 'SCIENCE', 4), ('LEADER_CATHERINE_DE_MEDICI', 'LEADER', '', 'CULTURE', 7), ('LEADER_CATHERINE_DE_MEDICI', 'LEADER', '', 'RELIGION', 2), ('LEADER_CATHERINE_DE_MEDICI', 'LEADER', '', 'DIPLO', 2),
Basically for each leader you want to play with, you need to add corresponding flavors for all victory types.
Maybe try with one and see if the errors are still there or if this would fix the problem.
