Downloaded the latest modpack today 9.15.50 and saw the Experimental Mod for Markers for Spotted and Flipped Tanks on the OTM (XMQP) When I installed this it disabled A LOT of other mods. When I reinstalled without this mod everything went back to normal. Installing that mod disables the following and maybe more:
Contour Icons
Hitlog
OTMs (puts it's own in overriding choice in modpack installer)
Server Ping in Hanger
Server Statistics in Hanger
Hanger Clock
Multirow Carousel
Auto Equip
Enemy Spotted Markers
XVM Stats (puts it's own in overriding choice in modpack installer)
Zoom settings
Player's Panel and Window settings
And that is just what I noticed...could be others. Sounds like a cool mod but not worth it if it overrides all of the stuff that it currently does.
