Playing Mazdumundi Vortex campaign, when an army enters a settlement unit upkeep changes from -25% to -39%. Change happens immediately. I'm running this only with SFO main mod and this sub mod. I had been running this with the 200% unit size mod, but stopped using it due to frame rate drops, could changing the mod be an issue?

Please look into this if you can, I'm really enjoying the mod otherwise, but the constant income changes make it hard to use.
