2. Open HuniePop_Data/resources.assets
3. See error

Expected behavior

Screenshots

Additional context
Here is the error I got from UABEA :

According to #345 asked a few days ago, huniepop is unity 4, but AssetsTools.NET only supports 5 and up. I've kept is this way because
A. I don't have any unity 4 games to test with
B. in order to work with unity 4, it will take some work on uabea's side to check between unity 4 and unity 5 to do things differently, making things a bit more complicated.
For now, this is an unsupported feature. Use UABE if you need something similar, which supports way back to unity 3.something.

I could, indeed, open the assets file thanks to UABE.
I feel stupid not noticing this earlier.
I'd be glad the tool had a Unity 4 compatibility, because editing the text assets with UABE (on HuniePop) makes crashs happen...

I'm looking into making Unity 4 support a thing in the future, but no promises.
