Blight many errors

1) During the game in the ENG version, the description of Blight and Blight-Ravaged maps has a quantity count at 25 and 50%, but in the RUS version, 20 and 40% are displayed there responsibly. (Sanctions?)

2) After the end of the battle with Blight, if the ichor pump is destroyed but not all bosses are killed, some remain and do not disappear. They don't disappear at all even after a few minutes. They just chase the character or stand on the Blight lines. (Summoned blight monsters not affected?)

3) After the end of the fight with Blight, loot falls near the ichor pump, but if the pump is close to the wall, loot falls outside the area where the character can be located and it is impossible to pick up loot. Imagine that an amulet for 300 Divines fell out there.. (Unlucky?)

4) Earlier, I reported the problem several times on the RUS forum and I was simply ignored. I'll repeat it here. On Atlas maps and on Blight maps and Blight-Ravaged maps, sometimes a situation arises in which it is impossible to build or upgrade a tower, even if you are close to the tower and Cassia too, and there are no obstacles to construction, there are no walls or chests nearby. Sometimes after about 50 attempts I manage to build a tower, but not always. An error rarely occurs, but it often prevents me from winning, which is very frustrating. (Still sane?)

5) Monsters get stuck in particularly narrow passages when you build a tower there. Perhaps this is not a bug and it is intended that way, but it seems to me that this is an abuzz of the landscape, which is why some maps with narrow passages are more expensive on the trade site. (Bug or feature?)

6) Maybe my PC is weak (2060 super and 9700Kf) but when I in Blight fight and many monsters are around it drops framerate a lot and freezes my PC up to 5 sec and instantly crashes ONLY when I use DX12. Switch to other do not crush game even on high load. Just think about it. (DX12 is bad on 2060 super?)
