Strange for me, this mod doesn't run with command line.
"F:\Program Files (x86)\THQ\Company of Heroes\RelicCOH.exe" -mod westfront -dev
(F:\\ it's my COH HDD installation)
using french coh+tov with last patch.
No command line problem with another mods: Blitzkrieg, grandeSP,Eaw,nhctov, eastern front,modern combat
