It seems there there is a problem when navigating between pages.
For example, go to https://topology.pi-base.org/spaces/S000029 (one point compactification of Q).
Click on the link to "rational numbers Q" in the first paragraph of text brings one to
https://topology.pi-base.org/spaces/S27 (notice "S27" and not "S000027", but that probably does not make a difference).
But the properties data displayed on that page is still the data for S29. For example, it says T2 = false and compact = true.
Refreshing the page then gives the correct data.
And then clicking on the back button to navigate back to S29 now shows the properties data for S27, which is also wrong.
I see this behavior both in Firefox and Microsoft Edge browsers.
