* Biomass generation fixed (watermelons gave 4 biomass instead of 24) (#71824)
## About The Pull Request
In the previous attempt to buff biogenerator in
https://github.com/tgstation/tgstation/pull/71563 it started using
`get_multiple_reagent_amounts()` proc which returned only the volume of
the first found reagent.
100 potency watermelons have 4 vitamins and 20 nutriments, so this proc
found 4 vitamins and returned only those.
Essentially, all this time biogen have been giving biomass for vitamins
only, and for nutrments when the plant didn't have vitamins.
## Why It's Good For The Game
They have been suffering this whole time. And cursing me for nerfing
biomass to abyss.
## Changelog
🆑
fix: biogenerator converts all plant nutriments into biomass, not just
the first found one.
