Building halfway and placed items gone

so i’ve encounter the bug 2 times so far. (no picture or video proof)

a furniture just become gone and a new one can be placed later though (i didn’t check inventory to count amount).

what happened was most furniture was placed but wall was 90% complete.

when wall is 100% complete, a furniture (mean bed) disappeared.

also i’ve got many crash report and screen won’t move much whenever i open craft menu for every jobs.
