[V6.29.0 - Ground Combat] Soldiers can walk outside the room boundaries

[MarcMDE]

After unintentionally destroying a wall that likely shouldn’t be destructible (2nd floor), soldiers are able to walk freely outside the room.

I also had full vision of the remaining enemies in unexplored rooms, as if being outside the room granted full visibility of the lower floor

Message for the devs: Great job on the game, you’ve done an amazing piece of work. So far, no truly game-breaking or disabling bugs have been found.

Alien visibility is a feature, not a bug (lol)

I also noticed this in a v6.29 alien base mission but neglected to report it -- thank you for taking the time to write it up as a clear and actionable bug report for the devs.

 

Re: the behaviour of "full vision of the remaining enemies in unexplored rooms, as if being outside the room granted full visibility of the lower floor". This is a special rule of how alien base missions work, described in the "further information" section of the alien base mission briefing:  "If there is a Xenonaut soldier and no aliens in the base control room, the location of all remaining aliens on the map will be revealed".    In the screenshot, your soldiers have cleared and captured the base control room, so it appears this rule is working as expected and the base control room is showing you where the last few aliens are.  I can see how it would be confusing given this "reveal remaining aliens" behaviour is unique to alien base missions and is happening at the same time as this walk-outside-the-room-boundary map glitch.

Thank you for the clarification. At first, I expected it to be a feature, as you described, but then I thought it might be part of the bug. Honestly, I didn’t take the time to double-check it.

Thanks, looks like the wrong type of wall was used here, we'll get this fixed!
