I am writing to here since I couldn't find any support section.
At the latest beta (0.9.0.0 staging 1742); at some owned properties, when you try to build blocks or demolish blocks, game erases (like/dumpcarried command) the blocks you are carrying with taking your ability to changing your tool permanently and the block you modified returns to previous state. This bug also causes server to crash to the last backup in 2-3 mins.
To summarize I think there's a deed corruption or something. I had a law in force stating "nobody can build, demolish or alter on any property which is not owned by them" when the bug first occured but even after removing it, the bug kept persisting.
With kind regards,
