with 2.0 i get this error:

It comes when saplings grow!

I haven't got time right now, but I'll look into this later...

Is this on a new world or one that was recently updated? If updated, has it been more than 15 minutes since you did?
Also if possible could you upload the world so I can reproduce the error, because I did a fair bit of testing before I uploaded the update, and I didn't manage to get it to crash.

Edit: Oh and are you using any other mods?

Found it out. Conflict with lumberjack! Now i have a new problem: the bags are in the planter but nothing happen...

Oh that's because I haven't got the progress bar working yet, it's happening but just doesn't show up

In the latest version it should no longer crash when used with lumberjack, but lumberjack still treats the saplings as vanilla trees so is works a bit weirdly

Ive also changed it so that the progress bar is set to 50% while saplings are growing so its obvious that something is happening, but havent made it increase as it would mean that I would need to make changes to the way saplings are stored and it might affect performance, although I might still do this in the future
