Issue with redstone torches placed in the same block space

[ghost]

Using the latest build from CurseForge, placing two redstone torches on the sides of two blocks facing each other (in the same block space) causes a crash. Here is a log: https://paste.ee/p/YF4mD

Having the same issue.

Here is the crash report: https://pastebin.com/44bWThdp

It appears to occur whenever two redstone torches occupy the same block and the server will crash when the chunk with the two redstone torches are loaded. Otherwise, everything thing appears fine and the server runs fine.
