Hi @AlexHerbert, I am not a MacOS user, but let me know if you would like to request a specific feature.  This goes for anyone, I am currently porting autociv to A28 and please let me know if you have any ideas!

The mod has an ammo cart unit that resupplies other nearby units.

Solution found: 1. Try to force start 0ad once from the terminal with options (Cite vladislavbelov) $ 0ad -conf=rendererbackend:vulkan If 0ad window appears then it's an OpenGL bug. Proceed to the next step.    2. To fix this permanently, add to your user.cfg this line: rendererbackend = "vulkan" Then if you run 0ad again (using any calling method), it should use the Vulkan engine.    3. If there are still additional errors, you can force debug output by adding this list to your user.cfg then run 0ad: renderer.backend.debugcontext = "true" renderer.backend.debuglabels = "true" renderer.backend.debugmessages = "true" renderer.backend.debugscopedlabels = "true" renderer.backend.gl.enableframebufferinvalidating = "true" renderer.backend.vulkan.debugbarrierafterframebufferpass = "true" renderer.backend.vulkan.debugwaitidleafterpresent = "true" renderer.backend.vulkan.debugwaitidlebeforeacquire = "true" renderer.backend.vulkan.debugwaitidlebeforepresent = "true" renderer.backend.vulkan.deviceindexoverride = "-1" renderer.backend.vulkan.disabledescriptorindexing = "true"   Explanation: Due to the recent Nvidia driver updates on Linux based OS, there are some OpenGL rendering issues and 0ad is one of the affected applications. If you force the backend to use Vulkan renderer then the bug is bypassed. However, you must ensure that your Vulkan layers are installed correctly. My Vulkan packages:   lib32-vulkan-icd-loader 1.4.335.0-1 vulkan-icd-loader 1.4.335.0-1.1 vulkan-tools 1.4.335.0-1.1  

@Perzival12 I made some changes to the Petra bot and committed it to the A28 code. Perhaps you can check it out there. Aside from that, there already exist some harder versions of AI bots around the forum, please have a go at digging around. Some may be outdated so require porting forward.  For the easiest level of AI, it would be a good idea to add back P3 and all the advanced units + structures, but really decrease the aggression level of the bot. What kills the human noob is not the late game units but the frequent early aggression.  On a separate note, let me know how well the AI bots perform with Hyrule Conquest  

Well, nothing has to guarantee that a formation will be kept in the heat of battle, it’s just mostly for initial positioning. "Everyone has a plan until they get punched in the face". How much a formation would be kept could depend on unit experience for example. Also, I was thinking about formation-inclined civilisations like the Romans, for others like Gauls I'd remove lots of strict compact formations. And maybe in some cases some could be added after some research, if historically relevant. All this would enhance the differences between civilisations and the tactics that have to be used for each.   But one wouldn't even know they are there unless using modifiers while choosing formation, it would be totally optional. Edit: and the panel wouldn't change size, what it's shown just switches between either formations, arrangements or priorities.
