Question Bug in Drink containers

I thought i was losing my mind after my game kept crashing. So i tested on a fresh GIT of tbamud. I have confirmed what I am seeing, and i am trying to fix this bug now. What happens is that name_from_drinkcon and name_to_drinkcon are not working as intended.

The keyword (liquid type) is to be removed and replaced with the new liquid type. However, we are getting a reiteration of that string, which deletes one word and places the entire string. This is a beer mug output, after i poured it out, refilled from fountain and poured out again. Normally I would just have "MUG WATER" but you can see what i get below.

Further testing shows that filling from fountain, then pouring out starts the chain reaction. I am keeping the output and debug in case Thomas wants to log into my dev server. I however have been able to reproduce multiple times now.

Thank you for the bug report. I know this is aprt of the mud that's seen multiple fixes over the years and seem to remember bugs allt the way back to circle 2.0 for this.
I'll have a look tuesday.

I wonder if this has something to do with that I sometimes gets really heavy drink containers. That is rather annoying.

No. That has to do with weight change name_from and name_to*, and if you dig back into D20, encumberage is something that needs to be accounted for.
