Hello! I might have found a new bug, at least, I couldn't find anything on the internet and I have already posted my problem in this forum (in general add-on affairs), where I got adviced to post my problem here. Here is the link to the thread: http://forum.kerbalspaceprogram.com/threads/137410-Science-Station-Mod-Experiment-Plant-Growth Short conclusion: If I want to start the Experiment: Plant Growth, I have to click on "Start Research" at the lab, right? The Problem is, that I get the message "no scientists", even I have 4 scientists stationed in the lab. I have fullfilled every other requirement to complete the experiment. Edit: I have these mods installed: - Deutsch Patch - MechJeb 2 - Greenhouse Mk1-master - Kerbal Alarm Clock_3.4.0.0 - KSPI_Extended_1.5.13 - ModuleManager-2.6.8 - Planetary Base Inc 0_2_7b - Station Science 1.5 - TAC Life Support_0.11.1.20 - TACLS Mining Edit: Problem solved: I have to delete the "Deutsch Patch" and the "Language Package" (which comes with the "Deutsch Patch"), then, the lab says "100% functional". Funny that this caused the problem.
