Globals not disappearing?

[PvK]

Remaining units of a dead faction don't disappear until their province is invaded.

Remaining enchantments don't dissappear.

These are known and I think not necessarily bugs but just how it currently works. I'd like to see the remaining units fight as independents. The spells remaining seem interesting to me as remnants of the previous regime.

I think some kinds of global enchantments resist some other existing types, even before 5 are cast. What were the existing spells, and what were you trying to cast?
