I haven't heard from anyone on the (active) mod team, but for those of you getting minidumps, there's no active workaround right now (members correct me if I'm wrong, I'm just trying to answer questions).
Note that almost everyone gets a minidump the first time they play the mod. This minidump does not repeat for most people if you just re-launch the program. I've noticed that disabling and re-enabling the mod can also give you a dump, and we had one the first time we played on ICO today (may have been because I disabled and re-enabled the mod).
Unfortunately, that's the extent of my knowledge. My driving fear is that there is something here that's rig-related, and that older rigs are going to dump no matter what the team does. Note that this is my guess only, I haven't done any troubleshooting because it hasn't been happening to me.
That said, a few of us had a good game on ICO today.
