We know that it released on epic games. When it actually comes to Steam, will it come along with Boston sprinter or will it come earlier? Also, I have around 30 mods installed. Will I loose all of them/will they be compatible when the new update comes out?
The updates and the Boston Sprinter are supposed to be released together is what I understand, as for the mods according to Matt the person who made them. Will have to redo them in order for them to work with the new version 4.26.
Not true. A version of the 4.26 update was released on the Epic release, but there will be other fixes and tweaks that come out when Boston does (including on Epic) It's been said on several streams that the summer update, including the move to UE4.26 will release at the same time as the Boston release Whether those mods continue to work or not is up to whoever made the mod. That person will have to rebake the mod in UE4.26, upload it to their distribution site and you'll need to download that new version and install it. Exactly the same as every DLC you have has been rebaked and you will need to redownload them.
