today inside a dungeon. someone opened a treasure box. and i pressed Select to go to the loot notice. the first time you Select it goes to the chat box. so you must press it twice. the first time i pressed Select the chat log was selected. the instant i pressed it again and selected the loot notice and before pressing X to open it. the chat log completely cleared.

however this is randomly occurring. it does not always happen like that in the same way. the next treasure chest it did not happen on.
