Please note that - unless you call the cataclysm-tiles.exe file launcher - the CDDA Game Launcher does contain 3rd party mods (and is a 3rd party tool itself) that may not be up to date.
Google connects the small_prybar to the More tools mod, which is not a mainlined mod.
This mod is - as far as I can tell - made and maintained by @TheGoatgod (which became the name I’ve definitely referenced the most to on this forum)…
Anyway, s-/he might be able to help you with that one.
The siphon bug however has nothing to do with him/her or his/her mods. It’s probably something related to the recent changes to the vehicle code.
I’m too sleep deprived to look further into that at the moment, but I left a bookmark and will come back later for that, unless it’s fixed until then.
