The no-physics function of the pickhax does not seem to work. Normally, one should be able to create floating torches, levers, gravel and water that does not start flowing by deleting the block beneath them with no-physics or delete half of a door without it breaking. However, the only block that does not get updated, at the moment, is sand, all others just get updated. A function similar to no-physics in VoxelSniper would be much appreciated (/b s mp , /v 0), though for shorter range.

Could you list what other plugins you are using on your server? I'm mainly looking for any other world-guard style plugins, but a full list wouldn't hurt.
Also, are you using a permissions plugin, or if not do you have permission: false in config.yml?
Finally, do you have useEvents: true or false in config.yml?

I'll try to repro the issue when I get home from work tonight, and any information you can offer about your environment will help.

I have this issue whe playing on the Voxel box, so I don't have this information.
You should be able to get it from Ciscog33k though, as he manages the plugins, as far as I know.

Yes, this is a known issue, and it only occurs at the VoxelBox. I've not heard of a reproduction of the issue from anywhere else. Some other plugin that they are running is interfering and applying physics after ToolBelt is done with the action. For any progress I would need to have them narrow down what plugin is causing the issue, so that I could work with the writer of that plugin to fix the issue.

If anyone sees a repro elsewhere, and/or is able to narrow it down to a particular plugin, then we can make progress here.

Yes, I could look through every voxel* plugging to try and find which one is causing interference, but that's not a bug in ToolBelt. I don't have time to go through all of their code to find which one is interfering. If someone wanted to test ToolBelt with each of their plugins, and narrow it down to one, I'd be willing to see if I could produce a patch for that plugin. Basically, if I can get my hands on an in-house reproduction of the bug, I'll do what I can. But I can't solve "it doesn't work for X server, while it works for everyone else".

IIRC, The open source Voxelbox plugins are kept at @TVPT, but they maintain a number of "secret sauce" plugins that are closed source.

Ok, thank you for your time and effort.

Apologies if I came off harsh in my previous comment. I really do appreciate bug reports and I wish to improve my plugin wherever possible. It just so happened that the bug you reported was one that I already knew about, and that has rankled me for a while. If the scope of the issue is ever narrowed, I'd love to help fix the offending plugin.

Please don't let my reaction above put you off from reporting issues, I am thankful when someone puts forth the time to let me know if ToolBelt is not behaving properly.
