Current behaviour:
When carpet is placed on the bridge, it will "disappear". But in fact, it will be placed on the ground below the bridge on the same tile. Other items (string of cloth, dioptra, kindling and a lot of other crap tested) works fine. Situation can be reproduced with small colourful carpet and meditation rug. I was unable to test other carpets, so probably they are bugged as well. It seems to be only carpet problem.
Expected behaviour:
either placed item should stay on the bridge where it was placed, or placing this item on a bridge should be prohibited at all.
UPD.
- dropping items on a bridge works correctly (so only placing from inventory is a problem)
- same weird behaviour noticed for unfinished cloth tapestries (all carpets are doomed here, lol). Finished cloth tapestry sometimes stay placed, sometimes - falls through, no idea why.
Workaround:
- Item can be placed on adjacent (non-bridge) tile and successfully pushed to the bridge afterwards.
