We are running a 5e campaign and seemingly at random for different players information from the spell book and other areas such as background gets cleared out. It seems to coincide at least in some parts to when the player and the GM is looking at the same spellbook at the same time, but not always does anyone know what could be causing this? How to fix? anything really we are still early in the campaign so its easy albeit annoying to correct as we get further in this will get more irratating
