Cannot fetch array @ 58a7ea

Hi devs, I pulled ghc gitlab repository by ``` git pull --recurse-submodules ``` But it failed with the following error. ``` error: Server does not allow request for unadvertised object 58a7ea0336363b29513164487190f6570b8ea834 Fetched in submodule path 'libraries/array', but it did not contain 58a7ea0336363b29513164487190f6570b8ea834. Direct fetching of that commit failed. ``` It seems the latest commit `58a7ea` of `array` library is not found on the server. Are there any help on this? Best, Taku Terao
