Hmm, that's odd but ok. The reason I say odd is because I got two different hacks for cresselia (3) and Palkia (2) and the Palkia worked fine but if you say so. As for the .rel files, the most recent battlefield one I got didn't come with one. Where can I find them?
Wait so it's not a custom stage you're replacing Spear Pillar with? You're just texturing the Pokemon? If so, then you don't need all three files. That's only if you're replacing the stage completely with a custom-made one. If you're trying to change the appearance of Cresselia, then make sure that .pac file is renamed to STGTENGAN_3.pac. For Palkia, STGTENGAN_2. For Dialga, STGTENGAN_1.
If that still doesn't work, then I'm sorry but I don't know what the deal is other than it's probably just a bad hack. But I've never textured Spear Pillar I've totally replaced it with a custom stage.
All .rel files can be found in the Data Partition in the Resources area of this site. But first, are you trying to port a stage over to another stage that it's not based off of? Because that's what the .rel files are for. If your Battlefield hacks are based off of Battlefield and you're putting it over Battlefield then you don't need a rel. You'd only need a rel if you want your Battlefield-based hack to replace let's say Smashville, and in that case you would have to download a battlefield rel (st_battlefield.rel) and hex edit it into a Smashville rel.

Just tried the TENGAN thing, still froze.
Answer what I said above.
