Tankentai

for be more  clear with the Battle Custom Hud

this can occur the battler don't do action in good time (like animated face )

this because Battle Cameras use a Alias method of "Turn_start", "turn_end"

but a lot of battle script use the BattleManager.turn_start (if I remember)

some script with tankentai  can occur weird little glitch like Moghunter ATB who when the battle start

this zoom but after the next turn this stop of zooming simply because he overwrite a specific section who make the battle camera stop to refresh the battle camera

I tried with your CTB but this result this annihilate the battle camera 

the reason why this do nothing is because Tankentai have a "Before_turn" who make a dezoom the battle but the section who bug is "turn_start"

the reason why is your battle system have data who handle this special turn system who are not recognize by the battle cameras who only use two method in the scene_battle 

the methods are here : 

alias turn_start_scene_battle_n03 turn_start def turn_start turn_start_scene_battle_n03 N03.camera(nil, N03::BATTLE_CAMERA["TURN_END"].dup) endalias turn_end_scene_battle_n03 turn_end def turn_end turn_end_scene_battle_n03 for member in $game_troop.members + $game_party.members N03.set_damage(member, member.sv.result_damage[0],member.sv.result_damage[1]) member.sv.result_damage = [0,0] @spriteset.set_damage_pop(member) if member.result.hp_damage != 0 or member.result.mp_damage != 0 end set_camera_wait(N03::TURN_END_WAIT) N03.camera(nil, N03::BATTLE_CAMERA["BEFORE_TURN"].dup) if $game_party.inputable? @log_window.clearso how you build your turn system don't use at all these method so the battle camera don't know when refresh.

for fix this kind of issue you can manually call the Camera zoom via these two method
