Confirmed
This looks to be a product of the new logging location. Need to figure out how to redirect my console to point to the new location.
Running a vanilla snapshot (13w38c currently) server and this is still an issue. View Distance 8 resulted in significant decrease in mod spawning. Setting it to default fixed the spawning issue, but some users started getting disconnect.overflow issues. Set view distance to 9, will perform further mod spawning testing.
Confirmed. At first, the player count is incorrect (still shows me as logged in in the count), but I am unable to connect. Refreshing after 10-15 seconds will reflect the correct player count, but still unable to connect. After rebooting MC, I can connect as normal.
