I tried to quick replace some yellow belts marked for deconstruction in my base with some red ones. Whenever I tried it made the placing sound but deleted the belt I was holding and did nothing.

After a quick test can confirm this happens with yellow to red splitters and undergrounds as well.

After more testing it only appears to happen with a set of belts that I planned for deconstruction a while ago and had a half belt of coal on them, I have since replaced them so I have no save to provide.

Thanks for the report. Do you have any mods installed? I can't reproduce any problems with fast-replace building over entities marked for deconstruction.

I do not have mods installed and I wasn't able to reproduce it, I'll stay on the lookout for it. Thanks for the awesome support!
