FillType Alert

This handy tool logs at game start which mods and maps try to register custom fill types (mod name, count, status) – regardless of whether the registration actually succeeded.

If the internal 255 fill type limit is exceeded, a popup displays the full list of all mod/map fill types along with their status (OK / Overwritten / Error). Individual fill types can be disabled directly in the popup to bring the count back under the limit. Your selection is saved to the savegame and will take effect after the next reload.

The popup can be reopened at any time via hotkey (Shift+F, customizable) or console command. A detailed in-game help page explains everything you need to know.
