After the most recent patch I noticed an odd slowdown when the rocket emerging from the silo animation is playing. I have never experienced this before and tried my best to search and see if this is a known thing or not but could not find anything regarding the crafting slowing down during animation time. There are some reference to the speed of the rocket loading animation but nothing saying it is affecting the crafting speed while in animation.

What is happened: When the animation for the opening of the silo and then again with the emerging of the rocket the crafting speed of the silo slows drastically.
What I expected: The crafting of the rocket parts to be unaffected by the animation of the rocket emerging.
Notes: The slowdown only happens when the animation is playing. this is proven when the doors finish opening the crafting speeds back up before slowing down again for the rocket emerging.

Let me know if you need anything else and I apologize if this is a known issue or is a "working as intended"

Is your power browning out?

No. This bug only happens during the animation of the doors opening, and rocket coming up from the ground. I am not even using half of my power capacity during this video I tried re-logging as well and the bug still persists.

Just got back home and checked my power over the past 10 hours and my accum charge is unused but I did see it spend some charge when the rocket completes but we are talking maybe 50ish MJ of charge is used of the 500 available. attachment is last 10mins so you can see the dip when the rocket completes

Not sure if to make followup posts or not but doing as much testing as I can in this save and though my power on the planet is not perfect the bug persist even when accum charge is going up (charging) which leads me to rule out any power problems. The bug is also consistent. it only happens during the animation of the doors opening and with the rocket emerging from underground. It also slows down at the start of the rocket launching off the platform but then resumes to normal while the rocket blasts off. It seems very tied to the animation of the silo.

Tested on Nauvis with a much larger power grid and can confirm it is NOT a power issue. The same effect happens there as well. Best I can say it is related to the Silo animation. I think the slowdown on launch is from the time the arms recede and then the rocket launching might be a separate animation and therefore does not affect the silo?

I am also encountering this. Same scenario, rocket part craft slows during the animation for a rocket emerging. As soon as the rocket is "locked in" upright, normal crafting speed returns. Also slows after launch and the door closing animation if the second rocket is not ready yet.

I also have plenty of power during the whole animation. ~500MW/2.9GW

Doesn't appear to be beacon/module related as I have tried with and without.

Thanks for the report. This has been fixed for the next release.

No problem and thank you for fixing. You all are the best.

I don't see it in 2.0.58 Changelog, it's there or will be on next ? Thanks for the fix (Had to put back a modules in my silos..)

It's fixed in 2.0.58, looks like it was forgotten from the changelog.
