So I ran a test with only UI Overhaul and these mods and was still running into the issue of the Support Specialization zones only having 3 building slots. I think I found the issue though. If you look in 00_zone.txt there is some code that may be causing the issue. If this isn't the issue then I have no idea what is happening.

planet_modifier = {
zone_building_slots_add = 3
}

Yah, I thought so as well so I have it installed and I am still running into the issue. Would you like me to share my modlist?

It's possible another mod is overriding this one. Try installing BPVMBS Compatibility.
@Antlantas

Ah, well that seems to be broken.

@Antlantas yes

Is this mod suppose to increase the building slots of the Generator Support Specialization, the Mining Support Specialization, or the Farming Support Specialization?

@yanganjili 你是不是用了作者的 BPV - More Building Slots - Compatibility mod？我发现是这个mod导致的环世界特化空白，禁用这个mod就好了

需要帮助，环世界的特化区显示空白，没有办法选择特化

特化怎么用不了

已修复@〇〇，〇〇

我玩着还是十个槽位

ethics and civics (4.0 mostly fixed +linux fix)使城市扩建区划变成只有三个槽位

我是直接扫描原版文件夹的，不应该会有遗漏，你还有别的模组吗
@swbot

哥，渔夫的特殊农业区划没变10个

打错字了，度假星球的记忆殿堂专精，下面三个可选的

@Hitachi 那是什么球，原版的不应该没被覆盖

发现了个bug错误的，独家星球的记忆殿堂只有3个格子

Thank you

@喵小夕 · F_thx thank you, very much appreciate such fast fix ^^

fixed
@alankraskow @CrasherFTW

@ 喵小夕 · F_thx I'm experiencing the same issue as @CrasherFTW, all buildings got ruined on on Farming Support district...

The mod is broken at the moment please fix it, city slots are non-functional / ruined if the buildings go more than the vanilla

@喵小夕 · F_thx mod给蜂巢星球添加的农业支持区划不知道为什么没法建造文灾飞的营养复合体，在原版的低槽就能正常造，我不清楚是本地更新了6个的数量限制导致的还是我这边mod有冲突。

@许多人 你可以尝试把特化槽位给开开看看，我这边是看着也是三个，但是特化区划开了后就是正常的10个

明天没空上群星，我星期五再排查一下qwq

我装的其他mod都是已经在兼容模组里面提到过的已兼容模组

@许多人 开局的兼容提示有弹你装的模组吧，除非你装的修改区划的模组没有被兼容

BPV - More Building Slots - Compatibility我已经装了，排序也是对的

装兼容模组呀 @许多人

这个系列其他的槽位mod都生效了，唯独这个区划的10槽没有生效，仍然是3个槽，以及mod增加的特化区域的建筑槽也是三个，只有原版自带的3个特化区域的建筑槽是10个

@BarbarianJoe21 Yes, the mod modifies all of them

Does this only apply to the mining, energy, farming districts, or does this also increase urban zone building slots too?

Isn't that supposed to expand non-city disctrict buildings slots? It appears not to.

可以加一个20槽的版本吗？底槽10的话，目前也有点不够用了

@Vhodnoylogin @lpdkwwsk now 10 slots

I'm little sorry: i only launched game, saw orbital colony and went for a walk.
Planetary distiricts really have 10 slots, but non-natural ones have only 6 slots.

似乎研究区划仍是5个，但其他的都正常

@Vhodnoylogin
Do you have any other mods that modify files in common/zones?
Errors may occur if another mod alters vanilla districts and overwrites this mod's changes.

Tested Scenarios (Functioning Normally):
Standard authority types (Hive, Machine, etc.)
Various planet types

Note:
Habitat districts (and similar celestial bodies) use urban districts (from a separate system).
All other districts have 10 building slots.

I told right about mining and food districts. I didn't pay attention to energy district, but saw then i have only one line of slots (10 slots got 2 lines) in food district.

@Vhodnoylogin
This mod modifies building slots in standard districts below and does not affect building slots in Urban district specializations. Urban specializations are part of a separate mod. I have personally tested this and it functions correctly.

Does it correct version of mod? It got only 5 slots, not 10.
