Is Shiv fixed on the unofficial patch? And will it be fixed with the next release - the bugfixes in RP 1.3?
I have an idea how to fix it:
1: Add a new proto (or whatever) for an item with the same stats as the Shiv.
2: Replace all the in-game Shivs with the new one.
I mean, it will be like adding a new item, but with the stats of the Shiv, right? So there couldn't be a problem? I don't think the problem could be caused by its stats - damage, price, weight, size, picture (it could be changed by a few pixels anyway), the skill it uses (Melee Weapons), the number of hands it uses, range, AP requirement, damage type, ST requirement, Burst Rounds/Ammo Type/Ammo Required, description, perks (they could be the cause, but they could be removed - better a worse Shiv than none) - I think this is the full list - just copy the Knife's stats, and change the settings I listed. I doubt any of them could be the cause.
Maybe the reason is that it's written as "undetectable" - maybe they tried actually making it undetectable and this broke it. Better a "detectable" Shiv than none.
