So since patch 75(awakening) gunner's recall has been bugged. The bug usually is failing to pull you towards the bot, but it still applies invincibility/iframe(typically). However there are cases where when you summon your bot -> recall that you may or may not get pulled but the iframe effect does not take place.
As for reproduction of the first bug, it seems completely rng and I have no means of reproducing it but you can see it in action in the clips below:
https://cdn.discordapp.com/att…6/2018-11-05_23-35-43.mp4 (retal -> recall, got effect as you can see by not taking damage from tail, but did not get pulled or the animation cancelled)
https://cdn.discordapp.com/att…2/2018-11-05_23-31-03.mp4 (remote trigger -> recall, got effect again but did not pull. You divine as well but it didn't proc, so the recall was what iframed the circle)
https://cdn.discordapp.com/att…0/2018-11-05_23-33-25.mp4 (retal -> recall, didn't cancel retal animation by pulling me)
https://cdn.discordapp.com/att…6/2018-11-05_23-11-05.mp4 (balders -> recall, didn't cancel balders animation by pulling me)
For the second bug the reproduction steps are quite simple as you simply summon the bot and recall a little before the new bot spawns, you could argue this is intended however the recall sometimes pulls and goes on cooldown but doesn't apply the iframe effect, which is strange.
