bug: Any Warp Item After The First Can Cause a Client Crash

[MrValenza]

Description

If you make a second item specifically for a warp and the cooldown is greater than 0, when you double-click the item to warp it will crash the client and not warp you.

Also, any warp item beyond the second item will also have the same issue.

Steps to Reproduce

Make two warp items.
Make one with any cooldown amount (greater than 0.)
Make the other with the same cooldown amount (greater than 0.)
Make a Common Event for each one, warping you to any place.
Link both items to their own respective Common Event.
Use each one.
The second one you created should crash your client unless the Cooldown for the item is set to 0 and nothing higher than 0. Any other warp items beyond the first will cause the same issue. This means that even the 3rd, 4th and 19th item that Warps will give you the same issue.

Affected platforms

Windows 11, Windows 10

Is this bug platform-specific?

• Yes this is platform-specific issue

Did you find any workaround?

As long as the Cooldown for any Warp Item is 0, you should not have any issues. The underlying issue though, is that you won't be able to add cooldowns to any warp items.
