Issue with Copy, append to self, undo/redo and freeze

[tnkz76]

Thank you. July firmware.
I’ll try to recreate it with a kit from the internal memory. If it works, I’ll create another video.
By the way, I’ve made this topic after this one :

Pattern Copy corrupting patterns

(I am on July-15, 2021 Firmware) When I attempt to copy a pattern (1) to a new pattern (2) either one or both patterns get corrupted in the process by omitting sequencing steps across various tracks. Playback is also affected on either one of both patterns - in one instance when pressing play, the sequencer would run once through the entire pattern without playing any of the step, except for the last steps on one track in the last bar.

It might be a mix of issues with copying while the sequencer is running and using the undo/redo function that reverts to a weird state.
