Hi,
what version of Unity? I have experienced a script totally disappearing yesterday, but I did create it myself, it wasn't linked to the use of the Ecosystem.
I'll keep an eye on this. The search time is definitly longer since the fix for the last json error, it's because it takes more times to query the github Server now, for no obvious reasons... so I had to increase the timeout, this is maybe what makes it feels less snappy.
Bye,
Jean
