Descriptive Problem Summary: When hiding paths from the object tree, it seems to cut off and clip itself after a certain amount of characters once you close and reopen the project. I counted 20 paths in my hidden object tree, but I'm more inclined to believe it has to do with character count since the 20th path was clipped as well to only show half of the whole path. I'm using Byond 509.1303 but I'm fairly sure I've encountered this before in the distant past.

Numbered Steps to Reproduce Problem:

1. Add a lot of object paths to the hidden object tree option.
   
2. Save the environment and re-open it.
   
3. Check the object tree. If enough paths were added, you'll notice some are missing towards the end of the list.
   

Expected Results: For the hidden object tree to accept any number of paths and hide them all.

Actual Results: It's only preserving the first 20 paths, likely having to do with a character limit of some sort.

Does the problem occur:
Every time? Or how often? Every time.
In other games? N/A

On other computers? N/A

When does the problem NOT occur? It doesn't.

Did the problem NOT occur in any earlier versions? If so, what was the last version that worked? (Visit http://www.byond.com/download/build to download old versions for testing.)
N/A. I'll test some other time though if this is necessary.

Workarounds: None.
