List of Detrimental Aran Bugs

This is a v83 Pserver, critical hits do additive damage instead of multiplicative, it simply adds 100% damage not multiply it by two. This got changed in later generations.
Example: Combo Smash lv20 does 700% dmg and when critically hit it will do 800%.

As for your first bug.. it's not informative at all nor does it make any sense. If you could put a screenshot of your attack range the admins will have a better understanding.
