Stuck AI turn when out of supply

[GabeKnight]

I've got this kind of error multiple times now with v6.1.9 and occurs when one or more enemy units run out of supply (e.g. encircled):
(it's a custom scen, but shouldn't matter in this case, I believe)

Code: Select all

That enough or do you need some savegame or whole output log?

PS: Sometimes it fixes itself with a reload of the "turn-end" savegame, but sometimes not...

PPS: There also a "check supply connection" trigger at work in this scen, like in the Norway mission...
