After leaving the game, my base at this control point disappeared and the enemy’s base took its place. But this base cannot be destroyed. When I approach the command center of an enemy base, I have the options (capture control point) , (abandon base). But when both options are pressed, nothing happens.
When creating a new base at another checkpoint, the building limit considers that I already have a base somewhere, because of this I have a limit of 8 walls.
It happened in single player. After turning off my comrades with whom we defended the base.
