Tried to upload screenshot but the file size limit is too low.   Something immediately noticeable upon switching to 41.50 is that visibility overall has taken a serious downgrade. The roof and tree hiding no longer works based on your character's vision and position, and now only seems to work based on character position, meaning you can't look into treelines or houses from outside even if you would have been able to in version 40.  I get that you're not supposed to be able to see through thick brush, but you have to be brushing up against trees to see underneath them, sometimes you don't even get to see your own character.  This is especially annoying when zombie's vision doesn't seem to be effected by trees at all, and can just spot you even with Inconspicuous through thick brush.   This is a consistent issue and I'm not sure if it's intentional or not, but regardless it needs to be fixed. Nort being able to look inside of windows in particular is  massive issue, and has caused me to lose characters to a bite I couldn't see coming.

hmm I'll try to hang around until it rains - unfortunately it's snowing right now and that definitely doesn't seem to stop it haha

I'm not sure if rain actually stops it, but.... PZ has this weird thing that, if you're not watching (as in, nearby enough to see) the fire burn, it basically never stops burning or advances

I'm doing the "A Really CD DA" challenge and well, you start in a house that's on fire, but I made it out just fine and have myself a base a bit away from the town. It rained for a couple of days but I wasn't near the fire at the time... Now I'm back in town and there's still fire spreading everywhere. Does it eventually stop or will it just ravage the entire map until nothing is left? lol Has rain been implemented to stop large fires at least?

I think it's scheduled to come at one point where farming gets revamped, though it might take a while. For a while, you can fill some of the gaps with mods.
