You will need to return to where you died to recover your items on your own.
TI CONNECT BAD TOKEN PATCH
With patch 3.15, personal player inventories have been introduced and players will now lose all of their carried items should they die, as they will remain with the player's corpse instead of staying with them upon respawning. To work around this issue, if you retrieve a ship at an ASOP terminal and are assigned pad 11 or 12, we recommend you store and retrieve the ship until you are assigned a pad other than those. We have identified an issue where a player on microTech traveling from the MIC-L1 Lobby area to a ship on pad 11 or 12 will be killed in transit.
