I have split the last two posts from the "How to get Simutrans-Experimental" thread and added them here since they appeared to be about this server rather than about how to download and install Simutrans-Experimental.
My apologies that you are having difficulties: I do not have time to look into it to-night, but please keep me updated with how things are going. TurfIt is in the process of writing an improved system for logging that should enable us to track down the issues rather better than is possible at present. An issue has already been traced to something relating to cities (we cannot be more specific yet), and Kevin/A-Train has identified a further possible issue relating to using the forest tool, although this is probably not the main cause of the problems.
