I upgraded 2 cities with 1 mycelium and chose super unit both times and they both ended up at the same city

Thats really weird

I guess you could say that cymanti has a lot of bugs

Can you check that you're on multiplayer v110?

Game version info is available in the replay

I'm sorry, I didn't watch the replay, I mostly use Discord on my computer and Polytopia on my phone.

#

@static creek Can you take a look at this? It's weird that it was mentioned two years apart and no one noticed it in-between.

I have saved the replay. Very interesting - will see when I can squeeze in some time to take a look at this 👍

I have another occurrence and I think I might know a root cause.

In this replay I got second gaami instead of workshop in the city to the west

I think this is issue with server side validation of the upgrade command. The only thing server enforces is that you are taking level up reward, but it totally trusts client data with regards to the type of reward as well as the city it is taken from.

I have two phones with the same polytopia account. Occasionally my son is watching my live games via my second phone.

It usually plays nice. The only caveat is - when city lvl up reward is choosen on one phone - it doesn't disappear on the other. Normally you can press any button after that and server will just say error and move on and everything is ok.

In this case I think following happened:

  1. I placed outpost which upgraded 2 cities.
  2. I chose lvl up reward for capital as gaami.
  3. Next I need to choose reward for lvl 2 upgrade, but before I can do it - my kid on the second phone choose gaami as a reward to get rid of the pop up.
  4. I picked workshop as a reward for second city lvl up

Since I needed to pick 2 upgrades in a row on the server side:

  1. First gaami was honored.
  2. Second request for gaami was honored cause it is time to upgrade ( target city and reward type were not verified)
  3. Request for workshop was rejected.

As a result I got 2 gaamies and no workshop.

@fast marsh Was your original issue on the same device or on two different devices? Do you remember?

Cool. I have absolutely no idea what's going on, so I'm going to leave this to Midjiate

Ok. I just confirmed that what I described above is indeed what was happening. While testing we were able to do a double border growth in a single city

I think in one version of the game - villages were spawning too close and can be taken with BG. Don't remember what happened then. I think they were 1 tile cities?

Unfortunately, this bug is decidedly exploitable.

Unfortunately it is 😦

@iron steeple So this is a problem. mrgr6808 has found an easily repeatable way to take inappropriate city rewards, notably including extra Super Units, and hilariously including extra Border Growths.

I like the use of adverbs in that last sentence.

#

Um, ty.
...Can someone test what happens if you take two City Walls?

quaint sequoia
#

Lol. Double wall?

graceful fable
#

Defense x16, lol

I tested it and it’s easily reproducible

dim willow
#

the implications of this are wild

#

double explorer for all the vision you need

#

double workshop for that early game eco

atomic cove
#

double explo and double ws works

#

lvl 4 city with 6 spt income and megaborders

#

next challenge:
3xBG

#

imagine the whole map (mostly) 1 big city

dim willow
#

yeah i was wondering if triple is possible?

#

suffice to say this is a major bug

# dim willow double workshop for that early game eco

You technically just misplacing upgrades and not getting extras. So double WS would be at a cost of 5stars lvl3 upgrade. I think with WS - you can essentially stick some of WS on capital so it is harder to siege and deny income. But yeah - you can game the system by misplacing upgrades for sure

@static creek Zoythrus was already pinged, but I know he's not a dev, and this probably needs attention.

I'll report this
