THX knightpress for this fix and thx for higher population cap to 500.
Happy to share and provide a fun mod.
Just to make it clear though, the higher population of 500 refers to the unit cap placed on the King Tiger, which would normally be a 1-per-map and now has effectively wide open building ability. If you need more than 500 King Tigers to kill anything then you're going to need a lot more help than I can provide
The game's normal population cap and population usage are still in effect of course, and I highly recommend using Ewiger Krieg in conjunction with the trainers available here at Cheat Happens if you want to have truly unlimited population.
