There is an interesting stat called IsImmuneToInvasion, there are 6 types
- IsImmuneToInvasion0 - Immune to Conventional Warfare
- IsImmuneToInvasion1->5 - All other invasion types
IsImmuneToInvasion0 is not defined within StatTypeDisplayDefs.xml and also does not have tooltip text within StatText.xml
For example, if added to an improvement. Once you hover over that improvement either on the tile or build list, game begins to generate a crash dump and crashes on the next click.
When I added IsImmuneToInvasion0 to StatTypeDisplayDefs.xml, it nolonger crashed.
