What happens when an uncontrolled mobile area effect, such as toxic cloud, slams into a wall or similar barrier?
Does it deform and spread out, creating a line along the wall?
Does it clip through the wall, effectively ceasing to exist?
Does it simply stop its movement, maintaining its original shape?
Does it change direction and follow along the wall (presumably following the lowest route per older versions of the spell)?
Can the effect be determined by the player and as permitted by the GM based on the nature of the toxic cloud as described by said player?

Short awnser: No rules for it.
i Guess you could have it Squich against the wall. but then it should spreadout aswell since i belive it should have the same coverage, at all times. so if 4 squares are "Squished into the wall" it should expand 4 squares trying to keep it circular form without extending anything "backwards"

Alternativly it could stop here since the center 4 squares of the cloud is against the wall. or it could flatten out more.

This would be the stop since how it cant expand anymore
But doing something like this would be time-consuming both on papper and in foundry. so a "simpler" compromise might be in order.
but it fell wrong with both the cloud dissapearing and it stoping when one corner hits the wall leaving "Safezones" against the wall.
