231 Devices

I now have up to slot 231 filled on a Aeotec Gen5 Zwave stick, trying to add another I get an error which is kind of understandable as 231 is the maximum. But I believed at this limit it should rollover and use empty nodes of which there's around 50-60.
I've ran the "remove failed nodes" command, I've put the stick into a windows pc & used Zensys tools to verify that there are empty id's

Any ideas? as it's not possible to use 2 Zwave sticks in Indigo, I'd like to use up the empty slots.

Can you copy/paste what you see in the Event Log when you try to include another module?
