Hello

I am using the newest ElementalCreepers for MC 1.7.10. But the console gets a lot of console spamming, which looks like it generate some lag spikes.

Is the spam it makes:

If you need more info/logs please let me know :)

That's due to changes in how GameProfiles work in 1.7.10. While EC does work in 1.7.10, it's recommended not to use it in that version. I'll have an update out for it soon that should fix it, but will break compatibility with 1.7.2.
