Fixed a bug with inline envenoming (e.g. SLASH KEROC ACONITE) and weapons that have a full stack of venoms on them.

Correct behaviour if you do an inline envenom attack with a full weapon is that the weapon gets wiped clean (announce post 2374), but this wasn't working. Now it is!

Penned by my hand on Closday, the 7th of Severin, in the year 475 MA.
