In `@lua/AI/OpAI/BaseManagerPlatoonThreads.lua`:
- Around line 1456-1457: Make both platoon splitters return immediately after
disbanding when the base manager is missing, preventing the unit loop from
disbanding the same platoon again. Update BaseManagerTMLPlatoon at
lua/AI/OpAI/BaseManagerPlatoonThreads.lua lines 1456-1457 and
BaseManagerNukePlatoon at lines 1510-1511; both sites require the same direct
change.
- Line 1061: Guard the assist-data access in BaseManagerAssistThread so missing
platoon.PlatoonData.Assist is handled safely before reading
BeingBuiltCategories. Preserve DefaultAssistCategories as the fallback when
assist data exists without BeingBuiltCategories, and ensure
BaseManagerSingleEngineerPlatoon can invoke the thread without a nil-index
error.
- Line 726: Update the caller around BuildBaseManagerStructure so success is
determined by StructureFound rather than requiring UnitName; when successful,
assign Engineer.BuildingUnitName = UnitName and break immediately, preserving
the issued build order even when UnitName is nil.
In `@lua/AI/OpAI/NavalOpAI.lua`:
- Line 49: Update the CreateNavalAI parameter annotation for data from number to
table so it matches the fields read by NavalOpAI.Create.
In `@lua/AI/OpAI/OpBehaviors.lua`:
- Around line 196-201: Update the repair polling loop around cdr:IsIdleState()
to check whether the commander has died after each wait and exit before calling
methods on a destroyed entity. Preserve the existing exits for Fighting,
Running, GivingUp, Leashing, and Cornered states.
- Line 302: Update the retreat loop condition in CDRRunAway so the distance
clause exits when the commander arrives at runSpot, reversing the current
far-distance check. Preserve the existing death, threat-clearance, and
health-recovery exit conditions.
- Around line 274-276: Update the enemy-count lookups used by CDRRunAwayThread:
replace the GetUnitsAroundPoint calls for nmeAir, nmeLand, and nmeHardcore with
GetNumUnitsAroundPoint so the subsequent numeric comparisons receive counts
rather than unit arrays.

string-valued BuilderType branch, while retaining the lookup used by the
table-valued branch. In the missing-builders error path near

disableTypes instead of directly indexing data.DisableTypes.
