Not sure about the first bug, never seen it happen before. The upgrade station has been fixed in a future patch.

Bug no. 1

Server Number: #16
Map/Mission name: Oxidize (Overclock)
Wave number: Wave 5/6
Time the bug happened: Wednesday, October 9, 16:36:52 (GMT -3)
Describe the bug: This Soldier was stuck, it would have made our wave impossible to beat unless we had a Pyro, which was the case. Regardless, it's still a bug, as it can happen with a match with no Pyro.

Bug no. 2

Server Number: #16
Map/Mission name: Oxidize (Overclock)
Wave number: Wave 6/6
Time the bug happened: Wednesday, October 9, 16:54:04 (GMT -3)
Describe the bug: I was able to use the Upgrade Station near the Robots spawn on the last Giant Soldier, is this intentional? I think it shouldn't be possible while in a wave.

(This is not the Inspect menu, it's the actual Upgrade Station, as you can see the clickable pluses).

Here's another screenshot showing the Upgrade Station open:

This can happen on Casino City. It prevents bots from picking up the bomb

Describe the bug: The Sentry Buster can't get through this door if the Sentry is placed somewhere in here [2nd screenshot], and it won't try going another way. It will also detonate itself when trying to go through the door (seen in the same playthrough on Wave 4/6).

A Samurai Demo got stuck between some rocks, around the front-right spawn.
First, an old one that I just remembered, from the first few days of the event:

Server Number: ???
Map/Mission name: Underground (Rustbelt)
Wave number: Wave 3
Time the bug happened: ???
Describe the bug: Giant Soldier got stuck in upper left spawn (but he eventually came down by himself).
Any screenshots: https://steamcommunity.com/id/automotive_gaming/screenshot/771730716927467904

Second, one from tonight but that I don't have a screenshot of, for some reason.

Server Number: #5 [PHL]
Map/Mission name: Snowpine (Raid Resort)
Wave number: Wave 2
Time the bug happened: Very roughly 22:15 (EST) on 2019-10-19
Describe the bug: Giant Phlog Pyro got stuck in the left spawn. I had to switch to Flamethrower mid-wave to unstick him.

Yeah, that's partially on me for making the boss a bit too frail.
I could consider disabling the spawns at the start of the break, but that would also make bots spawn right after the break ends, potentially stealing it from the Super Scout.
Of note is that the bomb is also reset before said Super Scout spawns, so it shouldn't interfere with the mission.

With the next patch, the boss'll be a bit tougher, so you should see this happen less frequently if at all - so long as you don't completely ignore the support.

Any screenshots: Not taken, didn't seem like it'd help identify the spot very much
