I believe Feralheart was made better. The new maps are of higher quality, less buggy, and the new animations, emotes and markings look great! Not to mention, every detail that the staff worked at for 3+ years was made in thought of how the community would benefit from it. For example, the removal of the buttswing and hip motion in the Headbang animation for the most part deleted the mating/raping issue in public maps and reduced trolling significantly.
It has also brought the community together, just when the population was at it's lowest. Heck, we broke RECORDS with the activity spike from the update.
However, I do understand and respect your frustrations, as nothing is without its flaws. Your issue can be resolved, however, by reinstalling the items and markings that have been updated and made 1.15 compatible.
