So, in playing as Great Britain one of my goals is to control 1.dian trade, and I have done well in that aspect. However, when I updated today to 1.9.1 from 1.8.whatever, I found India to be royally screwed up. Major provincial errors have arisen. They certainly aren't gamebreaking, yet they still suck, as reconquering said provinces will be annoying. What I noticed in particular:

they were my provinces or my vassal/protectorate's

they are now either uncolonized, owned by a different vassal, owned by a hostile neighbor, or owned by bloody Russia.

the only non-Indian province askew at the moment is in Siberia (Formerly Russian, now uncolonized)

a reload did NOT fix the issue

another game with the same mods 1 (Dynamic Candidates) had no issues.

Mods Enabled:

Flag Improvement Mod

Bigger Diplomacy View

Ironman is Enabled, so no cheating to fix it :( Any help would be greatly appreciated.

EDIT: the problem has been fixed by rolling back to 1.8.1
