Thank you.
I don't if it's too rustic to remove it, but it's working fine for me.
Code:
new c4 = find_ent_by_model (0,"grenade","models/w_c4.mdl")
if (c4)
entity_set_int(c4, EV_INT_flags, FL_KILLME)
The planted bomb keeps being shown in radar but the counter stops and no team wins, just like I needed...
