ServerPointer is the cause of WR crash. Do not add the ServerPointer in your code that will fix the problem (@k4m0t3 told me that and it works) when it comes to buster or crasher.
As for the fastreload, Im still looking for that addie. It was gone since version 4. Dont worry, if find it, I will post it here publicly so everyone can have fast reload without purchasing from the item shop ^^
Cheers
