PC Controller can no longer add nodes in 2.2.5

I'm not sure if this is related, but I just tried adding a node using my secondary UZB with PC Controller, for the first time since the update to 2.2.5 on my C7 hub, and it no longer works.

I've had a handful of Inovelli LZW42 bulbs, which of course pair with S0 by default. A month or so ago I removed and re-paired all but one of them using PC Controller, to get them paired without security. This went quite smoothly.

I finally went to convert the last bulb today, but when I tell PC Controller to "Add", it briefly says "Add Node Started", then almost immediately fails with the following message:

which looks like it's based on receiving a message from HE.

Any ideas whether this is due to a change in the HE firmware (@bcopeland perhaps)? I'm running 2.2.5.130, to be specific...

Well, I was able to resolve this by removing the UZB3 from HE, then re-adding it. That required a power cycle (and power removal) from the C-7 before it would add successfully, but after that it seems to be working again.

After this, I was able to remove and then re-pair that Inovelli bulb without the S0 security - mission accomplished: no S0 devices left!

It's certainly been a while since I last used the UZB - it's just been sitting plugged into a USB charger to act as a repeater - so I can't really attribute this problem to the 2.2.5 update. It may just have been coincidental timing that I went through this just after.
