Thank you for the PR, I do have some comments though.

#4588 attempted to do the same thing and was closed by Zonespace back in October 23 for the following reasons:

• Hivelords spending N minutes filling rooms with sticky resin is N minutes spent not building the things that actually matter, walls and fortifications. If they choose to spend their time building a more situationally-dependent room, then so be it.
• Sticky resin is incredibly cheap to destroy, being destroyed in 1 hit from almost every melee weapon and any explosion.
• It isn't very good UX to have to keep track of 25 cheap, destructible turf objects and destroy them if they're placed poorly (resin spikes are not an exception to this either)

I see that your limit is 50 instead of 25 from #4588 but please may you explain why this PR should be merged when it doesn't address any of the above feedback except for a larger number of built resins?

Sure!
Firstly, I never knew about that specific PR.
Secondly, in our current state of Feature Freeze there is no feasible way to overhaul builders without violating the lock. This solves the problem without a huge overarching overhaul.
Thirdly, we've historically preferred mechanical changes to things rather than requiring admin intervention. And in cases where we've had a builder coat a quarter of the map in buildables like this we've tapped them on the shoulder to tell them to calm down. (Feel free to chat up one of the hosts). This would prevent such situations from happening where even zoomed out ghost view cannot see the edges of the sticky/node field.
Fourthly, there's no good justifiable game reason for the mass fields beyond "It's funny." It creates a detrimental game experience that simply isn't fun for either side.
Finally, the cap is high enough that if you're using sticky resin in a deliberate targeted manner you should never bump into the cap, but if you're just filling turfs for the sake of filling turfs, you'll bump into the cap after filling your local choke (which is what you should be doing with them in the first place).

That said to address the points directly. The limit should be high enough that you shouldn't need to mentally track how many you have if you're not spamming them. The cheapness of destruction conflicts with spikes, but still "one attack" is a fact for sure, but imagine that across the entirety of lambda labs on every single turf. As for Hivelords building where they please, they still can, and the limit will nudge them towards working on productive defenses rather than things that are "funny".

This PR has been inactive for long enough to be automatically marked as stale. This means it is at risk of being auto closed in ~ 7 days, please address any outstanding review items and ensure your PR is finished, if these are all true and you are auto-staled anyway, you need to actively ask maintainers if your PR will be merged. Once you have done any of the previous actions then you should request a maintainer remove the stale label on your PR, to reset the stale timer. If you feel no maintainer will respond in that time, you may wish to close this PR youself, while you seek maintainer comment, as you will then be able to reopen the PR yourself

Feel free to make a new PR or bug me to reopen whenever you want to attempt the requested changes. Otherwise I could take a stab at it.
