No change after the 10th of june update.
Server not downloading newer version and disables the mod after world load due to an error.

The server now found and downloaded an newer version.

Now the same log Entry occurs like:

After the last update the mod loads without error message at startup.
The tool block is shown in the block menu.

But if I try to place the tool block i got kicked from the server and the block is not placed

I had the idea that the placed block of the last working version could cause the problem and i was right.

The visual 3D model from the last version was gone after the update but it seems to leave a "spare part" on the grid it was placed on. maybe a collider? or a part of the script is not deleted?

But in fact i had to remove the whole grid the old block was placed on. Luckily it was only a small subgrid. After that i was able to place the new tool block and use it.
