[Fixed- persists in 3.83] Hafted weapon quality bug

[rglory]

Combine decent or higher quality of the head and any grade of the haft, assembled results are always fine grade(Ex. fine spear fine shovel).
Didn't have chance to test lower grade materials.
And if assemble with perfect haft and disassemble, haft is graded down to fine.

I’ve rehafted rough axes with decent and fine hafts and got some decent, some fine axes.

I’ve not tried hafting decent axehead with a rough haft.

The max level product might be limited* to fine even if you use masterwork axehead. *namely CARPENTRY too low to produce MW/perfect items.

Yes, there was a bug especially with the poor haft quality not affecting the finished weapon quality correctly. The varying qualities were still plausible but with certain skill levels the results were pretty much always as reported here.
Fixed now.

This is normal and mentioned in news.txt. Dehafting always wears the haft to some extent and may eventually even lower its quality permanently.
