Description of the bug
I made a chamber with only a Neurotoxin timer (6 minutes) and two Neurotoxin vents. The building test chamber and Aperture Science logo screens don't have any issues, but at the point where the level would be loaded, I got an error saying "Instance lookup path "<ITEM_BEE2_NEUROTOXIN_TIMER:bee2_case>" returned no instances.". I have no clue what to do.
Expected behavior
I expected the level to load, as there was just a Neurotoxin timer and two Neurotoxin vents.
Steps to reproduce
Step 1. Create a chamber Step 2. Add a Neurotoxin timer. Step 3. Click "Start enabled" Step 4. Make the timer go to 06 (6 minutes) Step 5. Add two Neurotoxin vents. Step 6. Click File > Save as... (or Ctrl+Shift+S). Step 7. Rebuild.
Logs and Reports
Instance lookup path "<ITEM_BEE2_NEUROTOXIN_TIMER:bee2_case>" returned no instances.
Additional information
I'm using Portal 1 style and I disabled Multiverse Cave.
