Hello, whenever I use the keybind to use the spyglass, it works for a split second and then goes back to my previous slot. It only works while in my hotbar as well. All other aspects of the mod work.

Hi! Thanks for reporting this issue. I can't reproduce your problem on my part using spyglass improvements 1.2 forge. Are you using any other mods? Make sure that the keybinding for the spyglass in the controls menu is not conflicting with any other mod/keybind.

I am using quite a few mods, and no other buttons are assigned to the key. I did notice that the creative one works only if I don't have a spyglass in my inventory.

If you need it, this is the modpack I am using: https://www.curseforge.com/minecraft/modpacks/mbb-1-18-2/files/3778472.
