Playing the epic store version. I started a new game and found that I was zoomed in to the maximum on the geoscope. When I zoom out, the camera automatically zooms back into the maximum.
Tried playing a mission. Everything was fine until I tried to shoot at something. The targeting automatically went to free aim with maximum zoom. Tried to zoom out and the camera zooms back in again.
My mouse allows me to control the tactical map camera with no issues and is working fine in all other games, so it is unlikely to be the source of the issue.
