• When using an actually additions drill with max speed augments, the blocks become phantom where they still exist but you can't see them. It happens 50% of the time.
• When loading a world, playing for a while, exiting and try to load it again makes minecraft get stuck on loading world with 0% CPU usage.

These are some issues I've found that we're annoying. It would be great if they could be fixed. It could be just a problem for me, but I'd rather let you know anyway.

still an issue in latest version

I was unable to reproduce the phantom block issue but could be related to lag, especially on a server.

As for the "loading world" issue -- that is something I've heard multiple reports of but have no idea how to track that down. Going to need some more time and luck figuring out what that is.

I have this problem, too, from the very beginning of ATM3 and only in ATM3. And not internittend, always. There is no way to save /quit and restart a world without having to restart the pack from twitch. And therefore i think it is not a problem of the worldfile itself, perhaps the used RAM is not set free after quiting.... i have 8Gbte RAM and 6 Gbyte for Twitch

Is this still an issue? I know I had the issue before but haven't noticed it recently.

Forge related issue.

Updated versions of Forge fixed.
