I made a CTF map on Impact. I added two flag spawns for attackers (red team) and defenders (blue team) and when i go to custom game i can’t load the map because they are incompatible.
Please help. 
You have to set the item labels on the flag markers for it too be a CTF map, just setting them down won’t do anything.
Make sure you forge on the CTF game variant aswell.
I labeled them at CTF and it was created on CTF mode.
I ran into this problem making a dominion map and I cant seem to figure out which setting I have to tweak to make everything work.
On the item did you label them specifically flag markers?
And try saving it again, idk i plan on making a CTF map soon aswell so just trying to help
