Two issues running on this version.

The Rail Gun ability does not work or trigger. You have the coins in your inventory and when click the hotkey assigned to it, nothing happens. I have tried assigning multiple hotkeys just to test if it was the hotkey assignment and still same result.

Magnetic Manipulation - Does not allow you to throw blocks. The only thing you can do with it is when you have a conductive block in your hand you can use the ability to increase movement speed and then when you stop casting it consumes the block. I am not sure if this was the intention or not.

After doing some testing here is an update with respect to the railgun ability. If you are in ability using mode it doesn't work period. However if you exit ability mode and you right click with the coin in your hand you crash with an internal server error. The crash is client side not server side. Here is the error message:

http://pastebin.com/66dnR0Xw (ERROR IN SERVER LOG)
http://pastebin.com/Q5QCNGCQ (ERROR IN CLIENT LATEST LOG)

It appears to have something to do with the updated LamdaLib.

Both skills are rewritten so same error shouldn't be expected in next version.
