I recently started a new map today with a few friends. We played for at least 5 hours and did not see a single meteor drop so I am curious if it might be the seed or just how you PC handles Random Number Generation.
But the sound is definitely a bug. Quite often when I have seen them drop there is an echo with a very distinct delay so it almost sounds like 2 meteors falling at the same time. My guess is this might be caused by the Sound Filters.
I've had 2 meteor drops so far since the update ( I play ALOT tho ), both times they were bugged out (repeating loud booming noise), when i get closer to the noise i see the meteor glitching in the sky for a couple of seconds before landing. Once it lands the noise stops, Leaving vanilla stone & glowstone
Although i dont think the modpack needs anymore mods atm.. 1 or 2 i found for the future... Steamcraft 2! , Rails of War,
Inventory Tweaks & the add-on fix for the chests could be added client side, along with Journeymap & 2D animal icons addon (I also add Optifine & Fastcraft which i add for all packs I play to help with world gen)
Brilliant Modpack once again Wolf!
