Nine defects found during a whole-file audit of BaseAI while working on #2614, and deliberately left out of that PR to keep it reviewable. All nine are verified present on main at c9831b968; line numbers are from that commit. They are independent of each other — please feel free to claim one in a comment and open a PR for it. Most are a few lines. Small and self-contained DebugInterpolatedStringHandler compares tick counts directly — Projects/UOContent/Mobiles/AI/BaseAI/DebugInterpolatedStringHandler.cs:59 and :82: Core.TickCount >= ai.NextDebugMessage. Tick comparisons must be in subtraction form (Core.TickCount - ai.NextDebugMessage >= 0) or they break where the host counter starts large and wraps. See dev-docs/tick-counts.md. Deactivate() dereferences a null Map — Projects/UOContent/Mobiles/AI/BaseAI/BaseAI.cs:1103. Mobile.Map == Map.Internal is false when Map is null, so evaluation continues to Mobile.Map.GetSector(Mobile.Location) and throws. AITimer divides by Mobi
