1.0.7.9 Enemy settler vanishes when captured by settler - warrior escort formation *not a bug*

[mdaemate]

I tried to capture enemy settlers by my warrior who was escorting another settler unit. Captured unit just vanished without the usual popup. I tried again from autosave and breaking the formation before capturing and it worked as usual. I declared war whilst capturing.

If this worked, it might lead two settlers staying in one tile over a turn, so I guess there's a chance it isn't an actual bug.

Yeah this is well known as two Settlers can't occupy the same tile, solution is to break the formation as you discovered.
