Hello @GojiCloudspeed and thanks for reporting this issue! I've moved your thread into this already existing one, as to draw more attention from the developers!
It seems that this very old bug still exists in the game. I literally changed my keybindings to escape this issue, but that shouldn't even matter in the first place. Would like to see a fix one day for this.... I mean it has been more than a year for such a small weird issue.
@DYSPROssiumBug is still there after 1.5 years ....
and it affect new TX-130 too
Oh yeah, I completely forgot about this thread, so many BUGs it gets confusing. I just replied to 2 reports which are the same as in here:
