Haven’t made any more progress on that progress specifically. As mentioned I’ve planned to split the next update into two so I can get it out faster. First I’ll finish the update with everything but multi-tile units (networked multiplayer, major refactoring, transform-independent grids), as adding multi-tile units before this would just complicate making these changes later. I’m making great progress at that front, though, so in that sense I’m getting closer 
The next update is mostly feature-complete at this point, but there is still a long process remaining of testing, bug-fixing, structuring, commenting etc. Summer holidays is also going to slow down my progress the next few weeks, but I’m putting a lot of my free time towards getting it done in a timely fashion.
