TRes-egg race condition

Fiskbit

In build 251, I was waiting for a TRes fade egg to finish building (rapidly pressing e to use it, if it makes a difference). After the egg had finished building, but before it displayed the fade icon, a skulk hatched out of it and the egg was gone. Unfortunately, the timing for this makes it such that I can't really test it to make sure it's reproducible or still present in build 252, but given that it can cause a huge loss of team resources and might be easy for developers to test, I figured it's worth posting.
