Subject: [PATCH] Properly cancel usable items
|
|
|
|
This fixes the bug causing cancelling PlayerInteractEvent to cause items to continue to be used despite being cancelled on the server.
|
|
|
|
For example, items being consumed but never finishing, shields being put up, etc.
|
|
The underlying issue of this is that the client modifies their synced data values, and so we have to (forcibly) resend
|
|
them in order for the client to reset their using item state.
