Known Issues

IMPORTANT ISSUES

• Battle Tent is currently disabled – Rent Pokémon become BAD EGG and other stuff is busted. For now, the building is just blocked off by an NPC
• DexNav can occasionally totally bug out the game, best to save before chaining
• Cannot consistently replicate, seems to happen most often in caves?
• Level Reset Bug – seemingly for 1 battle, a Pokemon’s level is lowered, but they regain experience up to
  their normal level again after battle. Weird, and cannot be consistently replicated

VISUAL ISSUES

•  Graphics flicker after every turn in battle. This is semi-intentional! Resetting the graphics prevents many freezes and move animation
  problems.
• Battle Frontier buildings mostly use vanilla Emerald tiles
• PP number text is yellow when learning new move
• Swinub and Piloswine follower palettes bugged (Issue with pokeemerald-expansion:
  https://github.com/rh-hideout/pokeemerald-expansion/issues/5147)

OTHER ISSUES

• Pinball physics is far from perfect, but tbh I think that adds to the charm lol
