Summary

I'm currently using the plugin TAA Map Title Screen to display a map on my game's title screen. However, I'm running into a problem when I have VisuStella Encounter Effects enabled at the same time. The game does not load, and gives the following error: Spoiler: error message TypeError: Cannot read property '_lightContainer' of undefined at Sprite_Character.. [as createAlertFovSprite] (VisuMZ_4_EncounterEffects.js:1294)

I'm currently using the plugin TAA Map Title Screen to display a map on my game's title screen. However, I'm running into a problem when I have VisuStella Encounter Effects enabled at the same time. The game does not load, and gives the following error:

TypeError: Cannot read property '_lightContainer' of undefined at Sprite_Character.<computed>.<computed> [as createAlertFovSprite] (VisuMZ_4_EncounterEffects.js:1294) at Sprite_Character.<computed>.<computed> [as updateEncounterEffects] (VisuMZ_4_EncounterEffects.js:1294) at Sprite_Character.<computed>.<computed> [as update] (VisuMZ_4_EncounterEffects.js:1294) at Tilemap.update (rmmz_core.js:2332) at Sprite.update (rmmz_core.js:1987) at Spriteset_Map.Sprite.update (rmmz_core.js:1987) at Spriteset_Map.Spriteset_Base.update (rmmz_sprites.js:3158) at Spriteset_Map.Spriteset_Base.<computed>.update (VisuMZ_0_CoreEngine.js:8881) at Spriteset_Map.update (rmmz_sprites.js:3379) at Scene_TitleMap.createSpriteset (TAA_MapTitleScreen.js:974)

What it looks like to me is that Encounter Effects is trying to let events "see" the player, but since the player isn't on the map, it's not able to do that. I've made a demo project here that has this issue if you'd like to see for yourself.

I'd like to keep using both of these plugins -- I use Encounter Effects to make events chase the player if you enter their "line of sight", and obviously I use Map Title Screen to put a map on the title screen. I've tried other plugins that show a title screen map (including VisuStella Event Title Screen), but TAA's is the only one I've found with all the functionality I need.

What I'm looking for is some way to disable Encounter Effects on the title screen, or a way to modify Map Title Screen to have it load in a player character.

Alternatively, I could switch out Encounter Effects for a different plugin that provides the same functionality (enabling events to "see" the player based on the direction they're facing, and then chase the player down to initiate a battle). Any suggestions for other plugins that can do this would be very helpful.

Thanks in advance for any assistance!
