FTB Horizons Modpack

[Weiling]

Hello everyone,

Since the installation of the modpack horizon 1.0.9, (I already have those errors un 1.0.6) I have errors repeated in the console.
I looked on the forum, but I found nothing, or no concrete answer.

Here's my error:

That is not the console log. Please post your client console log.
