The problem probably happened today.
At first, I used a wand to place the sandstone,
It was in a state not to install more than 64 blocks.
After a while, I couldn't even place one block.
Other blocks can be used normally in any mode...
However, if it is creative mode, it can be used as usual,
Initializing config and server config, deleting and re-adding the relevant MOD, downgrading to Ver2.7 does not improve.
There is a possibility that it will spread to other blocks, so please let me know if there is a way to deal with it.

Alas, I couldn't do it.
If you normally set sandstone in left and right mode with a wand,
All of a sudden it was only halfway installed and then completely unresponsive.
If you're in creative mode, you can place it normally. Only sandstone can not be placed in survival mode.
Delete mods, configs, and server config files, start Minecraft, and then
Reinstalling the mod didn't fix the problem.
What the hell is going on?

Here is the most recent log. I wish I could be of some help.

For some unknown reason sandstone can now be re-placed.
Since the cause is unknown, there is a possibility of recurrence.
I would appreciate it if you could investigate when you have time.
