Hello, @BIS, I remember very well how one of the patches you added a feature to save the firing mode when switching the player's weapon. This way, the player would always retain the firing mode (single or automatic) when returning to their primary weapon.
However, this won't work after the swimming animation.
Every time the player returns to their primary weapon after swimming, they are given a single firing mode, even if their weapon was set to automatic when they entered the water. I made a video demonstrating the issue - https://youtu.be/qPTMPT5jRXI
Just keep an eye on the firing mode in the lower right corner of the player's screen, before and after entering the water.
