Often when I'm an Engi and choose wall from the placement menu, my forwards and backwards buttons stop working. I seem to be able to go side to side, but I can't forward or backward until I quit out of the wall placement mode. This might also happen with radars, and I'm not sure if it is side specific. It might only happen with BE. I'll try to clear these up while I'm playing in the future.
No! I'm an Engi on the go! I can't be standin' around all day makin' walls. I've got refineries to build, nades to spam, barracks to sneak into the enemy bases, Comm's butts to kiss, and Scouts to kill, APCs to drive, and tickets to waist.
Yes, I have a lot of tickets on my waist aswell. That way I can quickly insert one of them in my engy calculator whenever I need to revive someone.
I use my tickets to play Online Tetris on my engie calc. That's why you may find me standing in district at the middle flag seemingly doing nothing. But fear not, I'm pressing buttons. Waiting for that line. One day it'll come.
Hm... We went from tickets to tetris to Russian music . And re: OP, yeah, don't hold buttons when you open the various menus, it doesn't work so well.
