Don't mean to derail anything, but quick question.
I remember that in the orriginal version of F2, in Gecko, you could talk to Skeeter, a ghoul mechanic, while holding certain weapons in your inventory, and he would offer to upgrade a weapon in exchange for a 3-step plasma transformer. I know that you could find at least three of these, and after giving Skeeter the first, he would tell you, that he could always use more and would offer to upgrade more weapons for free as long as you bring him more 3SPTs, each of which would earn you 350 XP in addition to the upgrade.
On my current play through (with 2.3.2 mod) I can only seem to find a single 3SPT and skeeter only ever seems to offer a single free weapon upgrade. I did my best to check the patch notes, but did not see anything referencing that this was ever changed. Does anyone know if this is a bug or was this done on purpose for a particular reason?
