Timestretch beat replaced all my samples with the one I stretched

Long story short, when you get in a flow, things just fit together and effortlessly progress into a decent track, yeah… then I add a new sample, fairly long maybe 20-30 seconds that needs timestretching to fit my track, hit apply, place it on my track and hit play, turns out all my samples are now this one sample I just time stretched… what the actual fuck…

Obviously having been on such a good flow with this track I didn’t get chance to hit save… lesson learned i guess

Apologies, more of a rant than anything, just had to vent!
