I ran into an error when clicking Generate in the Build Sharing window with Export Support enabled. I dismissed the error, re-opened the build, removed an equipped item (Hands of Phrecia), and got another error. I attempted to re-open the build and found I could no longer open it, met with this error on every attempt to open the build:

Error:

How to reproduce the issue

Unfortunately, I can't provide exact repro steps as the build can't be opened to attempt to identify reproduction.

PoB for PoE1 build code

Uploaded XML for the build, as it can't be opened to provide a code: paladin.xml

Like the name suggests, it's a Paladin with a mostly typical aurabot setup. I had previously succeeded exporting the build as a support, but there were a lot of changes in between attempts so I've got no guess as to what change may have caused the error.

Start by inspecting Modules/CalcPerform.lua at line 2488 and the stack trace through Modules/Calcs.lua, then try opening the supplied paladin.xml. Trace how the boolean value reaches the arithmetic operation after the export and item-removal steps. Done means the build opens without this error and the failing calculation handles the affected value safely.
