What happens:
Arriving via foot/caravan at an item stash creates a small encounter map. Arriving via drop pod generates a full-size large map.
What you expected to happen.
I expect map sizes to be equal regardless of arrival method. I suggest making them a little bit bigger than the small encounter map, but not as big as a full-size map.
My request for a larger size encounter map is that the current small map is cramped and renders enemy mortars mostly useless and turrets very dangerous. It would also help players to grab some more resources while on the enemy map. I realise that's a suggestion and not a bug.
Repro steps:
Generate two item stashes (or savescum).
Use drop pods to get to one, use a caravan to get to the other.
Compare mapsizes. You will find one is quite larger than the other.
Ouch, so that explains how I saw different outposts on maps of different sizes and I remember the map sizes worked analogously to the aforementioned bug.
Fixed for A18, thanks.
