Describe the bug

Some items when dropped now are unstackable in inventory. I couldn't find any log data on this, only that it seems to have also been a recurring issue with the "Timber" mod some months back.

It seems that removing the mod from the mods folder and reinserting it fixes the issue.

Minecraft version

Relevant log output

Honestly I don't really know what to say to this x)
The NBT data is probably different and so they don't stack. But I don't really manage the drops part myself. I just ask Minecraft to do it.
With all the testing I did I never encountered that issue and without ways to reproduce it (other than randomly) I can't really investigate much.

If you can reproduce it "reliably" (like it happens every so often and no too rarely), is it with vanilla logs + vanilla axe or is there another mod involved?
