So i was playing one time and i guess the chat box just got annoying so i clicked the blue bar and dragged in under my screen. Now when i want it back, i cant seem to drag it back, i tried using z and it shows a little bit of the chat but it still doesnt allow me to drag it back up. flipping the minimap thing doesnt work either, so now im just lost in the game unable to communicate. i can talk but i cant read what they write...

reduce hud size?

Invert the map, it moves the box somewhere, it may help.

you could also increase the size of the box, just to find it/ get it moved to an easier to deal with place then resize it back
