Hi, I'm a veteran of many of the MMO flight sims like Aces High and WW2OL but brand new to DCS and I've been running through the Su-25t training missions to get my feet wet.
I got to this Internal Cannon mission this evening and I've encountered a pretty game breaking bug. As I'm flying through the gates and the instructor says "Watch your altitude at this next gate. It's a low one", he isn't joking. The gate is too low to fly through as only like the top 1/8th of it is even visible and the top border of the gate is below the tree line. I gave it the old college try but after 3 wrecks, I decided to come here and see if there were any bug reports about it.
I can get a screenshot of it if necessary but there is absolutely no way to fly through it without hitting trees because as I said, the top of it is below the tops of the trees.
(edit to attach screenshot): Here you can see the gate at the bottom of my HUD and you can pretty clearly see the tree tops extending up above the top of the gate.
