Known issues with SDK

I thought I would start this thread as there a few rather serious issues with the SDK, though different people seem to be having different issues.

1. Very few people seem to be able to build light unless they disable the lightmass setting (I however can build all levels of light with lightmass)
2. Some people are crashing when they try to build geometry (but not all)
3. Anyone who attempts to upload to Steam Workshop through the traditional SDK approach will crash the editor.
4. Most (maybe all) are unable to uplaod through command line approach such as KF2 as we do not have the WorkshopUserTool.exe in our install
5. One modder, SGT Joe was able to uplaod to workshop using the SDKFrontEnd.exe GUI program. Most users it seems do not have this in their install
6. Others have reported a crash when saving, though the map will save it crashes afterwards.

if anyone is having any other issues, post below and I will update this thread.
