pasting some lines causes weird error

ReplicatedStorage.PlacingSystem:171: Expected identifier when parsing expression, got Unicode character U+a0 (did you mean ' '?) 

line 171:

	    -- Update appearance immediately after creation

pasting and repasting fixes the issue instantly. removing the red error lines under.

my theory since this was uhmm a pasted code. it probably didnt fix some invisible characters. However this has never happened before. though the bug is easily fixable its a little annoying.

Expected behavior

everything to run smooth as usual
