The underground belt works for several minutes and then gets randomly stucked

[Lotte]

Same for me : but not for regular one, only with the tier 2 underground (the red one)

Happend to me with blue one (express) others seems to work nicely.

Same here, with tier 2. Works for several minutes after removing the stuck items, then got stuck again.

Same Fast underground works for some products but other products it gets stuck on

It is possible to place two underground belts in same tile and that can block the exit. You can check if there is 2 collision boxes in same tile with F6.

[Tami]

No, its not. Its randomly 1 lane or 2 lanes blocked, or (very rare) 0 lanes.

Thanks for the report. This will be fixed for 0.9.2. This is rather annoying bug so if it breaks your factory you can use a hotfix mod (see OP of https://forums.factorio.com/forum/vie ... f=3&t=2479) that temporarily solves the problem.
