This could happen if you skip v0.7.4 before upgrading to v0.7.5

Or has this happened entirely while using v0.7.5?

[bakerb15]

I believe entirely on v0.7.5.

Yesterday was first day that I added node. It happened immediately after adding the node. I then re-added and it was good for about 24 hours.

I'm going to attempt to reproduce a 3rd time. I do have a fair amount of technical skills, just not familiar with apple products; this is my first iphone EVER!
I'll try to figure out how to produce some logs if possible.

Kept the configuration for 3 days and just dropped it. This time i know it wasn't due to any upgrade. I found the .ips file associated with Zeus. I can post but am trying to ensure there isn't anything in there that i don't want public.

Switched over to iPhone for my daily driver to diagnose this.

Had this happen to me day 1 with a node connected over LNC

My theory is that the keychain is often accessed by other apps and that causes this value to not be fetched properly, which then leads to the rest of the Zeus keychain data to be cleared

if ([[NSUserDefaults standardUserDefaults] boolForKey:@"HAS_RUN_BEFORE"] == NO) {

perhaps not though.

Should be partially alleviated with #1561 - but there are still some cases in which it gets triggered without hitting the Restart button
