FWIW, when i installed PnP Celestials, it caused my TOB game to crash to desktop every time there was a dialogue...
some more detail: i've got a BP install which is working quite well - only the usual and aviodable BP bugs, no messed up dialogue strings - that i've been playing for about a month. last night i completed the SOA part and entered the TOB part, up to completing the first ('revenge') task in the pocketplane.
i installed the PnP Celestials today, and decided to summon a few to test them out. everything went smoothly until the planetar's limited wish dao gave us all the minor globe of invulnerability, when the whole thing went and CTD'd.
at the same time i realised the planetar had the wrong name: it was 'SHADOW MASTER' (capitals included). so i looked at it through DLTCEP and found its strrefs in the name field (74139 ad 74140 in this case) did indeed point to the name of and the description for the TDD druid kit 'shadow master'. i changed this to the strref that PLANGOOD.cre uses in my override folder (63489 and 63490) and saved the revised .cre to the override folder.
i cleaned out cache and temp folders, restarted, tried again, same result, CTD: except this time i noticed that imoen had just finished a banter with sarevok (this had happened the first time as well, i just didnt think it was important initially). the planetar was at least named a planetar, however.
i cleaned out cache and temp folders, restarted again, but this time didnt try summoning any celestials, instead did a ctrl-I to spawn a dialogue. got a tashia-sarevok dialogue, got a CTD as soon as it was finished. cleaned out cache and temp folders, restarted, tried again, same result. cleaned out cache and temp folders again, restarted, went immediately to saradush, avoiding any banters (i wanted to see if there was a problem with the pocketplane area or its .bcs). got melissan's speech, fight started, CTD before one round of combat was completed.
shut computer down (thought it might be XP not realising it had crashed), rebooted, restarted game after cleaning the cache and temp folders again, spawned a dialogue, got the tashia-sarevok dialogue again, followed immediately by the CTD. cleaned cache and temp folders again, restarted game, loading a saved SOA game i *knew* for certain worked, ctrl-i'd a dialogue: CTD.
uninstalled PnP Celestials, cleaned cache and temp folders, restarted saved SOA game, ctrl-i'd a dialogue: no problem, worked as it should. tried a few more, still fine. restarted TOB game, ctrl-i'd a dialogue (the tashia-sarevok dialogue): worked fine, didnt CTD.
conclusion: PnP Celestial isn't compatible with my install.
also FWIW: the deva .cre files in ...Celestials\Devas\Astral_Deva\Creatures and Celestials\Devas\Movanic_Deva\Creatures *also* had erroneous names: 'Priest of Auril' (strref 68214) for the astral deva, and 'Cerebral Knight' (strref 117480) for the movanic deva; in the override folder, however, and ingame, they had correct names - but the same strrefs as the erroneously named .cres in the install folders.
the Setup-Celestials.tp2 doesnt seem to indicate there's any dialog.tlk overwriting talking place, but something in PnP Celestials was clearly messing with it.
