[BUG] Escort caravan crashes

[R4MPZY]

I cannot replicate this myself but i have received several saves in which it is reproducible.

When you load the save you see the caravan is inside the town, and while waiting outside the caravan doesnt seem to leave and the game crashes.

Steps to reproduce the behavior:

1. Go to Saved Games
2. Click on 'Save004'
3. Keep waiting in campaign map and see the crash.

Tried the save 2 times, happened 2 times from both people that reported it.

Normally the caravan should leave the town and you can continue the quest.
