I am trying to get Simba working with SRL for OSRS but I appear to be getting an error every time I try to withdraw items from the bank.

The error is:
Runtime error: "Access violation" at line 103, column 15 in internal file "!addDelayedCore"
This is than followed by Simba hanging or crashing.

This occurs right after my script runs the line:
BankScreen.Withdraw(1, 4);
I am using the most recent version of Simba and SRL, any ideas as to how I can fix this?
