First, everything works well.
I use @cash to add a little cash to my admin char.
then I write a script which is an NPC with this command:
set #CASHPOINTS, #CASHPOINTS + 1000;
everything works well.
Then I sleep. My computer freezed in the middle of night.
When I wake up, I started my server again and re-test the NPC script.
Whenever I touch CASHPOINTS (@cash, script above...), client freeze (can zoom, change view, etc...), then server cannot connect (can login though) until I close server and start again.
What can I do now?
