Portals set itself to destination Portal, so we cant teleport between the portals
think it happen after server restart.
Replace Sign on portal will set it to other portal at destination, but happens again after some time

I think it happens after server restart, or maybe there is a problem with "LWC" plugin, cause our signs are private protected (so nobody can destory it)

Following is example from portals.yml
there i port from the first one (4010-1) to itself, it isnt set twice in the file.
i can port from the other around, (e.g. 4010-2 to -3 to -4 to -1,) but after ill hanging on the first portal

    4010-1:

Problem comes so much times.
after break and replace sign it works correct for a while

in the portals.yml isnt a double entrie for the sign,
but ive notice, that it is always the first portal of the group
