PlotSquared restriction direction bug

[Hdadaw]

Debug paste link: https://athion.net/ISPaster/paste/view/1851055e534e40fe918f0027388b6f95

Description of the problem: Any player without //wea or any bypass permissions (this bug was found by players on my public server) can do any WorldEdit operation, for example *//set outside merged plot in directions South-West and North-East. Video with a detailed demonstration: https://youtu.be/iematG2mBvk

How to replicate: Claim and merge plots like demonstrated on video or like this and try //set, taking the points inside your plot so that inside the selection there is a territory outside your plot diagonally in the directions South-West or North-East, like showed on video: https://youtu.be/iematG2mBvk

[NotMyFault]

Your ticket has been closed because it falls into one of the following categories:

• Your issue has been fixed in a newer version of FastAsyncWorldEdit for versions 1.8 - 1.12.2, get the latest build here matching the platform you need.

• Your issue targets minecraft version 1.13 or higher. This is the wrong repository then. Move to this repository and open a bug report here. BUT BEWARE: You should consider updating to 1.15.2, using the latest Fawe build for 1.15.2 (Build 255 when writing this, get it here) and reproducing the issue in a clean environment (fresh setup Spigot or Paper server).

• Your issue has been fixed in a build of FAWE for 1.15 or an issue exists on our new repository.

• You either didn't fill out the template or deleted it.

If none of the bullet points suits, head to the second one.
