NullPointerException when rendering OrthoList #13

Closed alexdcramer closed 3 days ago

alexdcramer commented 1 week ago

Found in the process of fixing #12. As that fix allowed preloading of scenes, this bug has become more apparent than it previously was. I'm assuming that this bug has been in existence for awhile, as I made no changes to the OrthoList. Here is the stack trace:

...and here is the orthography

===Orthography Start===
m:p'
bʲ:b'
n:m
p:n
b:p
t:b
d:t
k:d
pʲ:k
===Orthography End===

Granted, it's a bit busted already (this file was used for testing when orthographies were first added), but not to the point where it should be unable to render orthographic data...

That was a surprisingly easy fix! The OrthoList still isn't the most... functional component, but that's for a different issue.
