ACU not spawning

every time i make a custom game on seton's clutch, my acu model is not spawning, i can't build structures, and the UI is set to tier 4 (i could build experimentals). there are no errors or info, it just stops working like it was paused(tho i can use the menu and subsequently - pause) it all happened after the last update. my modpack consists of:
-total mayhem mod
-extreme wars mod
-black ops ACUs , EXunits and unleashed
-commander survival kit
-RK's explosions
-resource rich x5

that is all the info i know. i really hope it helps get me back to my favorite RTS game

It is because of RK's Explosions. See also:

thank you very much, it was the last mod I suspected of breaking my game
