When copy pasting a lot of chains, sometimes apollo stops launchpad ouput afterwards

[YarosMallorca]

Description

When copying a lot of chains and pasting them into another group, apollo stops outputting lights to the launchpad after updating UI, only re-opening the project fixes the issue, no need to restart apollo completely. Also, I should note that ANY lights play, not only the chains I just pasted, all the lights from the project do not play!

To Reproduce

Create a normal 8-page setup in apollo like shown in the tutorial video (mat1jaczyyy's channel) and insert at least 20 chains with pretty heavy effect chains (maybe less, haven't tried with less than that, maybe it depends on how heavy the chains are), then copy all of those and paste to another group (page), then try to play any of the effects using the launchpad, they will not display. After re-opening the project it goes back to normal.

Expected behavior

Apollo should paste the chains like normal and continue playing the lights as normal, without disabling the output.

Your setup

OS: Windows 10 Pro - 64bit (update 20H2) Apollo Ver: 1.8.3 Launchpad: Pro MK1

Additional context

Haven't tried to reproduce on mac as I don't own one. The problem appears on my windows machine running the latest build of apollo and windows (at least when posting the issue)
