I use =BTC=Revive =BTC=Revive
and tried an other Revive Script by norrin
(it's on armaholic)
I changed as you mentiond "respawn =(to) "Instant" " but changed nothing. In BTC it spawned me into water in my misson and in the other script it did nothing i stucked in unconcious screen.
Maybe these scripts do not support instant respawn?
I have found that it works with INS Revive script but can i set the amount of respawns? for ex.limit it to 10.
