I have checked EDB and i haven't found any gaps because i haven't changed any entries connected wit sicily (sycylia) and saxons (elektorat saski) factions. This message appeared after changing faction jerusalem in descr_sm_factions (religion, facton colours, culture).
After thouse errors log says:

07:46:17.546 [script.err] [error] Script Error in mods/potop/data/world/maps/campaign/imperial_campaign/descr_strat.txt, at line 4015, column 59
you have chosen an invalid tile(249, 249) for Gerhard (jerusalem) 

I have checked names and descr_names files but i haven't found any discrepancies.
What can be reason of this problems?

The character one is easy - it's a bad placement - correct the co-ordinates in descr_strat (not fatal).

The building one will (could) be related to the conversion from settlement to castle and vice versa. Make sure all cultures are in the faction requirements.
Else you have the culture\faction in the settlement building (town watch) but not in the castle building (mustering hall).
