As i said i let the Geoscape run for 6-7 months without killing any ship or doing any mission. Nothing happened. Perhaps i should do what you said and check the points where the supply ships land.
Maybe it's just too early for alien base... It's simple - if don't see any supply ship then play until aliens decide to build base.
xvi is not yet implemented on the battlescape - so there is no civ attack you (and if it's there [i've never seen this], then it's a bug)
Well, that's not actual XVI, it's only single scripted mission as was said somewhere on this forum. At least i understand so. But the fact that my soldiers were attacked by civilians at least once per campaign - i can confirm. How it works - you are shooting aliens as usual but some civs are tagging around your troops (alien are shooting civs but not those). If they found any dead alien (there is no any dead soldiers usually
they pick up weapon and kill my soldiers with fullauto from plasma rifle. If you retry mission that will repeat. Last time when i encountered such behavior i had to collect all weapons into backpacks to prevent armed civs. Killing them counts as bad actions anyway...
Do you have any save (the trunk one is better) before such missions?
No. If i got such i''ll attach somewhere here. Right now i started new game on hard difficulty but progress is very slow mainly because of bugs in dev version. I just can't end battle without crash. last time it was this:
Nokim has taken control over team 1.
[STATS] Nokim (Kim Dekkers) kills alien (Abtrenek Zt Hrmokuk) with Full-Auto of assault_ammo (entnum: 60)
Team 1 ended round
Team 7's round started!
