I'd be swapping out those nock in the back end with the black Eagle style. They tend to have a sharper angle on the edge of the nock. I've had those nocks before and swapped them out, in my opinion the edge was a little soft or rounded for my liking. To easy for the string to want to roll over a softer edge
Maybe I missed it, but was it the same arrow that does it everytime? In the same orientation each time?
If it's not the same arrow each time that would suggest to me that it's a common problem throughout your arrows and the common denominator is the nock.
I am hunting with the same arrows I shoot in practice. This has actually happened with Excalibur Diablo bolts and Cabelas Carbon Hunters.
Never an issue while shooting at the range. Never a mishap; only on stand after a few hours sitting there.
Both sets of arrows using different nocks? Still sounds like your string is rolling the nock cause a partial dryfire.
I would follow Peters advice and sand your nocks then try to replicate the situation that is causing the problem
Might be best to just pack it up and send it to an authorized excalibur service center and just let them check it out . Do it in the off season while you not using it.
This sounds like the smartest idea so far.
Personally, before sending it out I would put some double wall heatshrink on the arrow retainer. I like my arrow retainer to touch or almost touch the mainframe but with heatshrink on it. It is almost impossible to have too much tension on the arrow retainer but it is easy to have too little.
BTW, going over the nock is possible but I've only heard about it with some lighted nocks that had really rounded corners. When the string did go over the nock, it left a mark on the upper 2 vanes.
If you think your bow is screwed up , Leave the bow cocked at home for 3 hours then shoot it at your target . Should hit the ground in front of it , Right ? But I can't see the limbs losing power then regaining their strength again.

Agree and I should’ve done it while it was cold outside. Like I said before only happened when bow was cocked and hanging on stand in sub freezing weather.
I’ll give that a try come fall when temps drop
