So I created a function file (altar.mcfunction) and typed in a bunch of commands that made the function size 2kb. All my other functions were 1kb in size and could be run using minecraft:tick ,/function, and be called from other functions. only altar.mcfunction could not be called anywhere. it's contents are attached to the report. However, if I change the contents to make it 1Kb in size (I deleted everything and put in "give @p cobblestone"), I can suddenly call altar.mcfunction like the other function files and it executes the command in the function successfully.
