To help identify the cause of the crashes that came in between versions 1.18.0.1944-f2cae8d6b
and 1.18.1.1966-10fc2f8d3 , I am producing server development builds to be tried out. I will send you links by Private Message.
If you have disabled the graphics card, please re-enable and confirm the crashes are still occurring and then install the versions I will send you. Note that if the version number is lower than what is installed, you would need to do an uninstall first through Add or Remove programs
I am making the builds available to users that I have seen evidence from and I confirmed the issue
