Thank you very much for your help, however the solution was very stupid.
You need to have these CVAR's:
PHP Code:
mp_backup_round_file ""
mp_backup_round_file_last ""
mp_backup_round_file_pattern ""
mp_backup_round_auto "0"
In this case we can reset player money and weapons directly on player_spawn hook.
However I think that that
2nd Problem still exists and somehow we need to write extra code to solve this problem.
