No, we are using Calamity and a couple quality of life mods (smart doors, auto trash, etc.)
We have zero RAM problems. Please read what I said above <.<
We even tried on the 64 bit launcher so we can use our full RAM. Changes nothing.
Our PCs, again, are FAR above what we would need to run this.
Also, on the previous version we played Calamity, TOGETHER WITH OTHER CONTENT MODS, and had NO PROBLEMS!
Our hardware is 100% up to the task EASILY. Speedtests say our internet connection is constantly fine. We are not using any other content mods right now.
It all began with the Calamity update.
So please don't say this in such a condescending manner when I already explained that we were using these mods in the past with no problems. And now we are using up LESS RAM than we did back then since we aren't using any other content mods. So something changed for us with this version.
So yeah, I didn't list any other mods, because we aren't using anything else.
PS: Just to satisfy your curiousity I quickly did a fresh install and ONLY used Calamity, no music, no quality of life mods, and quickly went to summon the eater of worlds, since the problem was most apparent in worm like enemies. And it's the same. He teleports all over the place, even when I literally exclusively have Calamity installed, tons of RAM to be spared, stable Internet connection, etc.
Again, this new Calamity version messed something up for us two.
