When I start the game, the loading gets stuck at PlanetaryBaseInc/BaseSystems/Parts/Utility/Greenhouse/Greenhouse_g/KKAOSS_Greenhouse_g

Hm, looks like the dev doesn't care about solving this bug

Please do not assume that a developer does not care about a bug because they did not respond fast enough for a project that is not in active development for quite a while.
This error does not happen in the latest version of (an unmodded) KSP. Hence it is very likely that this problem happens because of an incompatibilty with another mod you have installed.

For properly reporting a bug, please follow the instructions in the forum article linked in the Support and bug reports section of this projects description and provide the required information. Without said information it is not possible for a developer to even guess what the problem could be.

In short, following information is required:

• Version of KSP
• Version of this Mod that is installed
• Log files for KSP
• Mod that interferes with KPBS (including version)

Please especially pay attention to the Clean Environment steps described in said article. Downloading, installing and
rummageing through potentially hundreds of mods is not feasible for a mod developed by someone in their free time.
