This is related to https://forums.factorio.com/viewtopic.php?p=495921#p495921 - Krastorio2 has a flying-texts.showOnSurfaceText stored inside of global. In 0.18.28 functions are removed from global on save (they will be missing only in saved output).

as a work around just place down brick, concrete or something similar and you will pickup the biomass and be about to build on top of it, only problem is sometimes you won't be able to pick the concrete back up, and if you try use the jack hammer to pickup you'll get the error

Last game update broke a lot of our scripts.
Don't worry we are working on this problem.

Fixed for Krastorio 2 ver : 0.9.19, that will be released soon.
