Hi After using 0.6 of fastcraft my server crash and i think because of this plugin seeing the crash report.
using spigot 1.9.2

After starting the server again with 0.6 im getting spammed with this error and whole server starts lagging:

Can you see if you're still getting this error in v0.7

ok will check .. sorry i did not see 0.7 but now after refreshing i do.

Still getting this spammed : http://hastebin.com/ecubomigoc.avrasm
and if you try to mutch its getting laggy again.

not sure if this helps as it constantly say this plugin with your have a conflict but this is the tools stats.

I'll take a look at its code to see what's causing the problem. This is the only error you're getting?

over and over and over till it lags and possibly also caused the crash if lots of players triggers the error.

I just released v0.8, and it's compatible with ToolStats for me. Let me know how it works.

ok will check .. atm to many players so cant do it right now.

ok just updated to 0.8.
Look good as errors are gone for now.
Will run it for 2 days and give you feedback on it again so i can gather some results also from other players.

As while testing i still had some strange behavior with it like slow response when you click for example the crafting table for crafting grid.
At a certain point i was even able to get the crafting table in my own inventory for the crafting grid.

Performance issues mentioned here: #19 and #15 (not sure why the guy changed the title of that ticket, he had a different issue before which was resolved)

Performance has been improved greatly for v0.9.

ok just to add a finishing note to this closed ticket and already outdated fastcraft+ 0.8.
0.8 seems to be fine no errors anymore or crashes.
