Enemy stole my gun, no waypoint to get it back

[Joltyboi]

im farming sargus ruk for orokin cells and twice in a row now ive had the dreka master yoink my secondary (which is a kitgun, not sure if this is kitgun specific or not) out of my hands and theres been no waypoint to get the thing back like there normally is, at least im assuming it was a dreka master, a scorpion pulled me over to it on my last run and after my warframe got back up my secondary was gone, so im not sure, either way im losing my secondary and if its the dreka masters stealing it im getting no waypoint to get it back like there normally is, which you can imagine is annoying
