Bugs on PTR after the last patch

I noticed that towers are now shooting again, but the armor is gone (no more indicator), priority between heroes and minions when tower diving seems to work. Attacking minions still get the same indicator as if inspired but have their movement (and attack?) speed decreased.
On Warhead i encountered a game breaking bug after attacking a burning fort mid. After I nuked the fort it started burning as intended, but when i attacked the fort, it not only increased the burn duration, but the burn spread to (visually) all minions, friend and foe (no damage done to minions) and heroes, friend and foe, and without visual indicator also to me, stopping me from channeling not only the tunnel entrance but the hearthstone channel. After I died the burn effect lasted on the ground where I died, spreading to minions and heroes that walked past it. The effect was still going on my character (Falstad), at one point killing me. After I attacked a burning structure (bottom keep tower) again it got removed until I attacked a burning structure once again.
An allied Diablo AI got stuck in the animation to channel the nuke, the nuke didnt fire and after Diablo was killed still in the animation of firing, landed on the ground.
