Can you report the errors you're getting upstream? @ShadowOfHassen

That's strange, also expect the performance to be way worse.

Very nice. It also adds the missing tooltip when the starting turret can't be placed. Do you want to open a PR? I can help with testing and reviewing.

Welcome. Specifically, how do you plan to help?

Good catch for the cached entities.  Alright I think I've finished this up so we might have it now. Cool enough by replacing the method to retrieve snappable entites, a couple vanilla bugs for fixed just like that; notably the inability to continue wall placement in fog of war, but also inability to build from captured walls. I've listed all features achieved in opening comment. I've tested everything I could thing of to see if any exceptions are left unhandled but I think everything seems so much better now then it ever was. 

Hi everyone, I'm "El Maker" (it's not my real name) and  I love playing 0 A.D. !!  I've been playing 0 A.D. for a few years now (I’m not very good at it, but I really enjoy it!). After discovering this amazing project, I’ve developed a genuine interest in helping its development and contributing in any way I can. I’ve already explored the forum and found several topics that inspired me — there are a few areas where I think I could help or bring new ideas. I’m highly motivated and would love some guidance on how to get started ! My ideas (or areas where I’d like to help): –First of all : the civilisations such as Etruscans, Numidians, Nabateans or Dacians (I've seen that there are a lot's of civilisations that you want to add so I can help !) – Secondly : improve the Gaïa system (not fauna or flora but the "humans" : pirates, itinerants bandits ...) --> I've seen that in the Big Eyecandy section (but anyperson anwsered me) – Thirdly : (it's not THE ONE but I would be cool in my opinion) change the starts of every civilisations (in order to have different beginnings of games and strategies that really change depending on the civilizations) Any advice or feedback would be greatly appreciated. I’d love to collaborate in this amazing project !! Thanks in advance for your time !! El Maker
