Delete and undo, can't retrieve deletion in list

[TIMAI2]

There is a bug in the latest release nb200. Do not delete any blocks that are in sockets - they will not go to trash or be recoverable by undo.

Help test nb200a

This one has suddenly started working will monitor Nope, doing it again Is it because there is a textbox1.text block already there ? Seems to be blocks that are in a socket. Standalone single blocks delete to the Trash. Blocks in sockets just delete and disappear. Same issue if I delete blocks from the right click menu. This could be a big problem, given there is no delete warning dialog anymore.
