Thank you very much for working on the suspension issues and fixing them in 3.1.0. I really appreciate the quick response and the work you've put into the mod. I’ll keep playing with the mod later, and if I run into any other issues, I’ll report them to you.
As for the Bastion machine gun issue, I was using the Farthest camera setting. If I aim at the front armor or the tracks, everything works normally. However, sometimes due to my own mis-aiming, I accidentally aim at the center of the tank, such as the middle of the chassis. When that happens, the machine gun can rotate toward the rear of the tank because of the position of the aiming point.
The turret model and the main cannon still remain pointed forward — only the machine gun changes its firing direction. This is especially noticeable when using a mod like Blue Armor Overhaul or another mod that changes the projectile color, since the trajectory makes it very easy to see.
Once I move the aiming point back toward the front, the machine gun rotates back and corrects its position after about a second.
I hope this helps with reproducing the issue, and thanks again for the continued work on the mod!
On the Bastion machine gun firing backwards: I haven't seen that one myself. Which camera setting were you using, and were you aiming at something close to the tank or at the tank itself when it happened? That will help me reproduce it.
