During your visit, the slow loris housed at Pangolin trail is the Sunda Slow Loris, while the one at leopard trail is Ah Pui the Javan Slow Loris. The education team never bothered to change his signage.
Thanks! This means I saw both species

The Javan was going to be a new species for me, so I paid attention to the signage.
Overall I was not disappointed with the number of species I saw at NS. Only the Malayan tiger (I only saw the white tigers), clouded leopard and bushbaby were no-shows, but apparently the latter was off-show due to births. I think I saw every other species that was signed
Sunda Pangolin, spotted giant flying squirrel and collared owlet were new species for me as well! It was also only my second time seeing hog badger and small-toothed palm civet, and my first time seeing them active
Does NS still keep nile lechwe? They were neither signed nor mentioned on the tram ride.
What about Asian swamp eel? I saw them at River Wonders, but ZTL also mentions them for Night Safari, but I did not see them or any signage. Are they still there?
It was also very interesting to see how many species are able to co-exist with pangolins.
There was the pangolin/palm civet mix (did not see the pangolin here), the pangolin/tiger cat mix (pangolin was the dominant species here) and the pangolin/slow loris/flying squirrel/mouse deer mix (did not see any interspecies interactions)
Honestly, I'm not sure if gharials are nocturnal, but for some reason they seem to be kept at the Singapore Night Safari too. If anything, I think they're often kept in bright areas like other crocodilian species.
I don't think gharials qualify as nocturnal, but it was really cool seeing these giants submerge and than reappear again into and from the darkness of their pond.
Also, seeing 3 zoos with Indian gharial in a few days time was really something. Previously I had seen the species at 3 zoos only, so that number has now doubled!
