MIXER - Mixu's Unlocker
How should I modify the building slot limit?
I used this MOD in version 6.0:

I could get 8 slots in the secondary town of my original IE map, but it was no longer possible after 6.1. I could only get 6 slots at most. No matter how I modified the pack, I could only get 4, 5, or 6 slots, and could not get more than 6. Then I found out that MIXER had limited the slots in the secondary town to only 6 slots. How can I modify the limit on the slots in the secondary town in MIXER? ?
