I was playing on my friend's server on Grounded 2 riding my pet soldier ant into the red ant hill when his game crashed. I relogged onto his server to find my pet ant is no where to be found even though my pet is in my buggies list. I figured maybe it's a one time thing and it wouldn't happen again so I got another soldier ant pet. About 30 minutes later exploring near the picnic table at the snackbar front region I crashed. When I relogged I could not find my second soldier ant pet. It was sorta frustrating since I had to go into the ant hill twice to get the red soldier ant egg only to lose my pets twice. 

same thing has happened to my friend on my server

So you completely lost it? As in you can't call it back through the wheel?

yea, sometimes it gets lost completely and sometimes it's in the nest thing. We just had 1 soldier ant egg always ready so if the buggy gets lost we can take another one instantly.
