Summary

I have just updated to the latest UEFN version 26.10, and now my player movement is glitching.
By glitching, I mean the position of the player will (seemingly) randomly reset to a position the player was at a second or two previous.

It doesn’t do this continuously, but occasionally (I haven’t yet pinned down the timing of this) - and it does seem repetitive.

Jumping around a map has a serious issue due to this glitching.

It seems like a bug has been introduced with the latest update, as this is certainly new since the update. Nothing has changed in my island since I last ran it (in the previous version of UEFN prior to the latest update) without any such glitching.

Steps to Reproduce

I don’t have steps really?
I run my island, and when moving I am teleported back on a seemingly random timeframe, but I guess it happens every 7 to 10 seconds.

Expected Result

It wasn’t exhibiting the odd behaviour prior to the 26.10 update.
Movement was normal, as expected.

Observed Result

Glitching player position

Platform(s)

Only running on PC during development of my island.

Just a quick followup here, as I may have encountered a dawning realisation…

Long story short, I recently had Fibre to the home installed, and my existing router had to be swapped out due to a faulty WAN port. I swapped it out with an older router that “works”, but I now suspect my issue is related to this older router giving me packet loss, and not the game at all!

I will follow up after more testing, and hopefully a new router.

Dammit…

Sorry for the probably erroneous bug report!

Rob

Final update…
New router resolved my issue!
Glitchy old router - not a problem with UEFN, thankfully! :slight_smile:
