I've installed GG5.1.606 on my test server in my "warmup_round_start_default.cfg" I have the below addons. When I restart the server, warmup will work fine with deathmatch and no elimination, players respawn back right away in the game. But when the map changes, gg_warmup_round.cfg doesn't seems to be loading the addons in "warmup_round_start_default.cfg". I and up in elimination mode for somehow.
gg_deathmatch 1
gg_turbo 1
gg_elimination 0
gg_knife_pro 0
