[Bug] Selection tool in Canyon will not paste correctly any selection mixing blocks w/ pillars & blocks w/o

[Harest]

Hi,

Cf. title, i had the issue earlier by selecting a part of the map to replace it. It correctly selected all the items but on pasting, only 1/4 of them got pasted. I then tried things out, and i found that if i was taking both the blocks without pillars automatically places and items with them, it'd not paste the selection correctly.
By selecting either one or the other, it worked as intended. It was 100% reproducible in my case, i've a backup on the map in the state where it was when it happened if needed (in private). There was vanilla items, embedded items and most were placed using the snapping. Which is probably the cause here too.
