Target out of range regardless of actual range

Date & Time: 5/17/2018 & approx. 4:45PM EDT
Frequency: Sometimes
World name: Mateus
Character name: Ruto Lhauske
Retainer name: N/A
NPC name: N/A
Monster name: Various, includes all bosses
Class/Level: Summoner/70
Party or solo: Party, 4 people
In-game time: Unknown
Area and coordinates: Hells' Lid Dungeon
Housing: N/A
Steps:
1. I entered Hells' Lid via the Expert Roulette
2. Starting with the flaming wall monsters, I started to get "Target is not in range." alerts whenever I tried to cast any offensive spells.
3. I moved to multiple ranges in regards to the enemies, and still was not able to consistantly cast offensive spells.
4. Sometimes I was able to get "in range" by standing pretty much dead center of the target's glowing selection circle.
5. During some encounters I could cast spells initially, and then I began to get the range alert without warning.
