Just as a note, if you swap between weapon sets, the effect of 'you have iron reflexes' is removed, so there is code for adjusting this.

Bug probably exists for all items.

Add Augyre. change it's effect to ResTech and the problem exists for this item. (check saved .xml)

I have a fix for this but it comes with complications.
PoB appears not mean't to delete configuration option settings.
So my fix works correctly when the item is deleted. You can save and reopen the build and all will work as expected.
This fails in the following circumstances, before exiting the build and re opening it:

• Ctrl-Z is used to bring the item back.
• the item is re-added.

In these two circumstances, the configuration option for the item MAY appear to be set to it's previous value, but it isn't. Saving and reopening the build will reveal that the configuration option wasn't restored.

So if this complication is acceptable, I'll add a PR.
