Describe the bug

When I create a region, the region creates it for me where I have done previously // pos1 and // pos2, but when I go to see the actual region which area it covers, I notice that the region is shifted by
+0.5 blocks to West and North and -0.5 blocks to South and East
This is very annoying in my PVP region, as some players can hit mid-block before entering the pvp region
To Reproduce

1. ... //pos1 x,y,z
2. ... //pos2 x,y,z
3. ... /rg create TEST
4. ... Check the exact position of the region block by block

Expected behavior

checking the region margins block by block, even if using / rg info test (or in the regions.yml file) gives you the correct coordinates, the region is offset by 0.5 blocks in West and North
Screenshots

Additional context

In the screenshots I only show the offset of the North direction since the other one did not have time and making a new region annoyed me
ah for the record the bug does not depend by the stair, I have already done various tests, the bug does it with all the regions even in different positions and places

Update FAWE to fix the bug

1. unsupported environment
2. we use whatever coordinates the server tells us your player is at, we're not doing hitbox checks or something to see if you're overlapping more than one block.
