I'm having the same error as another player in the comments:
___________________________________________
############################################################################################
FATAL ERROR in
action number 1
of Alarm Event for alarm 0
for object obj_server:
buffer_write argument 1 incorrect type (string) expecting a Number (YYGI32)
at gml_Script_write_int
############################################################################################
--------------------------------------------------------------------------------------------
stack frame is
gml_Script_write_int (line -1)
gml_Object_obj_server_Alarm_0
Let me know if you can get the servers up and running again :)
