Water overlay + bugged POI block space

[TheBlueLazu]

I've run through the current threads and didn't seem to see anything related to these unless I'm not reading it as the same issues I'm having. Apologies in advance if that's so.

First issue is a long term I had reported a few times in A19 that I had hoped would be solved in A20. It might be an AMD gpu based issue but I get this crazy water overlay effect on my screen once I've been around any water depending usually on what direction/angle I'm looking no matter where I am after that.

Second issue is A20 based as it seems like we have a 1x2 space (like a stop sign size space) that we can't build into as if it thinks something is still there. We weren't sure what the purple edged outlines on block spaces were for a moment but figured out it meant the block was going to be placed in an unsupport spot and fall. But it's not so much to do with the purple block space as it that there's a spot we can't place *anything* but can build around/ontop of (of course it collapses though without support). We've tried CM mode to use the dev gun to remove anything around it and hopefully something we couldn't see but it didn't work. I went to try the POI menu option to clear out the space with the blue selection tool but apparently that got removed some time during A19.

We're not sure what was there but know its directly over an edge of the bear cave under ground (the incomplete construction house) and I have a feeling it was in the area out back around the cement mixer that we salvaged (but thats a 1x1 block space so not sure what else was there anymore). This could probably be solved by some tooling of sorts but I'm personally at a loss as its a minor bother impeding a build we're doing.


Thanks in advance and LOVING the update so far. Seems like loot is a lot better now and the initial bloodmoon is way more balanced.
